plastic polymer alloys which are suitable for processing into films, containers, tubes and other devices which are particularly suitable for medical applications.

Prior art

In the medical field, beneficial agents are collected, processed and stored in containers, transported, and finally infused into patients to achieve a therapeutic effect through tubes. The materials used in the manufacture of such reservoirs and tubes must have a unique combination of properties. For example, in order to be able to visually inspect solutions for particulate matter, the reservoirs or tubes must be optically transparent. The material used to make the walls of the infusion solution container must be flexible enough to cause the infusion walls to collapse during infusion to prevent air from entering the reservoir. Such material must be functional over a wide temperature range. The material must therefore be functional at low temperatures, ie. it must retain flexibility and rigidity, as some solutions, such as certain premixed drug solutions, are stored and transported in such containers at temperatures of about -25 to -30 ° C, in order to minimize drug degradation. On the other hand, the material must be functional even at high temperatures to be able to withstand heat during sterilization, a procedure applied to most medical and pre-shipment packaging for nutritional products. In a sterilization process, the container is usually exposed to steam at a temperature of about 121 ° C under elevated pressure. The material must therefore withstand this temperature and pressure without substantially collapsing (ie it must have sufficient dimensional stability at temperature).

To facilitate processing into useful products, it is desirable for the material to be weldable at high frequencies (RF), usually about 27.12 MHz. The material must therefore show sufficient dielectric loss to convert high-frequency energy into thermal energy.

Furthermore, such materials are required to have a minimal impact on the environment when disposing of products made from them. For products that are landfilled, it is desirable to use as little material as possible and to avoid introducing low molecular weight leachable components into the material during their manufacture. The material should also be light and have good mechanical strength. Another benefit is obtained if the material is recyclable by thermoplastic processing of the used product into other useful items.

For containers that are disposed of by incineration, it is necessary to use materials that eliminate the risk of biological hazards, ie materials that burn minimally or not at all, environmentally harmful, irritating or corrosive inorganic acids or other products that are harmful, irritating or otherwise unacceptable.

It is also desirable for the material to contain, or contain only small amounts, low molecular weight additives, such as emollients, stabilizers, etc., that could be released into drugs or biological fluids or tissues, thus endangering patients using devices made from it or contaminating substances. stored in containers of such material or processed in facilities where such materials are used. In containers in which transfusion solutions are stored, such contamination could result in release into the transfusion pathway, which could result in injury or death to the patient.

Traditional flexible polyvinyl chloride-based materials meet many and in some cases most of the above requirements. Polyvinyl chloride (PVC) also has the significant advantage of being the most affordable material for the construction of equipment that meets the above requirements. However, PVC can produce an unacceptable amount of hydrogen chloride (or hydrochloric acid) when its flue gases come in contact with water, leading to corrosion of the combustion equipment. In addition, PVC sometimes contains plasticizers that can be leached into drugs or biological fluids or tissues that come in contact with polyvinyl chloride materials. Therefore, many materials have already been proposed to replace PVC. However, most alternative materials are too expensive to implement and, in addition, do not meet all of the above requirements.

Many attempts have been made to develop a film material to replace PVC, but most attempts have been unsuccessful for some reason. For example, the material described in U.S. Patent No. 4,966,745, i.e., a multilayer film capable of resisting steam sterilization, cannot be welded by high frequency dielectric heating, which precludes the use of this fast, inexpensive, reliable, and practical method for assembling structures made therefrom. film.

European patent application EP 0 310 143 A1 describes multilayer films meeting most of the above requirements, which can be welded by high-frequency heating.

However, the components of these films are amplified upon irradiation, so that the films cannot be recycled by standard thermoplastic treatment methods. In addition, irradiation releases a significant amount of acetic acid, which remains trapped in the material. In steam sterilization, acetic acid, as an impurity, migrates into the packaged contents and, by changing the pH of the contents, acts as a potential chemical reagent that can react with the contents or as a catalyst causing its degradation.

The main object of the present invention is to provide thermoplastic materials which are in all respects superior to the above-mentioned materials hitherto known to those skilled in the art or used commercially. Among the properties of these materials that are important are flexibility, ductility, the ability to recover from deformation, not only at room temperature, but also in a wide range of temperatures from ambient temperature to refrigerator temperatures. Such material should be sufficiently optically transparent for visual inspection and should be steam sterilizable at temperatures up to 121 ° C. Furthermore, this material should be able to withstand significant deformation without deformation whitening, which may be a physical or cosmetic defect. Another task is that the material can be joined by high-frequency heating. Furthermore, this material should not contain substantially low molecular weight leachable additives and it should be possible to dispose of it safely by incineration without the formation of substantial amounts of corrosive inorganic acids. Another requirement for this material is that it can be recycled after use by standard thermoplastic processing procedures. Furthermore, it would be desirable to be able to use crushed waste material falling off during the manufacturing process in order to save material costs. Finally, the material should be a cost-effective alternative to the various polyvinyl chloride materials currently used in the manufacture of medical devices.

In the production of alloy-type compositions in which several polymers are mixed together, it is difficult to meet all the above requirements at the same time. For example, in most cases, such polymeric alloys scatter light and thus do not meet the requirement for optical clarity. The intensity of light scattering (measured as haze) depends on the size of the domains of the components in the micrometer range and the proximity of the refractive index values ​​of the components used. The selection of components that can be satisfactorily processed to form domains of small size and at the same time with minimal mutual deviation of the refractive index is generally a very difficult task.

The invention provides a solution to these and other problems.

The essence of the invention

The thermoplastic polymer compositions of the invention show significant improvements over the prior art. These materials can be processed into products of a quality suitable for medical applications, such as bags for storing medical solutions or tubes for transporting medical liquids, and can also be used for the product of other products or parts of products, such as connectors, adapters, manifolds, valves. , lines, catheters, etc.

8) resistance to autoclaving, measured as the flow of the sample at 121 ° C at a load corresponding to a pressure of 185 kPa, 40% or less, preferably 20% or less, and

9) its deformation whitening does not occur at deformation at a mean speed of about 50 cm / min and about 100% elongation.

The polymeric compositions according to the invention satisfying these physical properties contain several components. The three-component compositions consist of a first component which is a flexible polyolefin imparting heat resistance and flexibility to the composition, a second component which is a high frequency susceptible polymer imparting high frequency heat sealability to the composition and a third component compatibilizing the first and second components. The high frequency susceptible polymers used in the present invention, which are characterized in more detail below, should exhibit a dielectric loss of greater than 0.05 at frequencies in the range of 1 to 60 MHz and in the temperature range of ambient temperature to 250 ° C. The first component should comprise 40 to 90% by weight of the total mass, the second component should comprise 5 to 50% by weight of the total mass and the third component should constitute 5 to 30% by weight of the total mass. Another embodiment of the three-component composition of the invention consists of a first component imparting high temperature resistance to the composition, a second component which is a high frequency susceptible polymer imparting high frequency heat sealability to the composition and imparting flexibility to the film and a third component compatibilizing the first and second components. The first component should comprise 30 to 60% by weight of the total mass, the second component should comprise 30 to 60% by weight of the total mass and the third component should comprise 5 to 30% by weight of the total mass.

The four-component compositions of the invention comprise as a first component a propylene-based polyolefin, which may contain isotactic and syndiotactic stereoisomers, as a second component a non-propylene-based polyolefin, as a third component a high frequency susceptible polymer imparting high frequency weldability to the composition and a fourth component compatibilizing polymer. The first polyolefin component is preferably polypropylene, which comprises about 30 to 60%, most preferably 45% by weight. The second polyolefin component is preferably ultra-low density polyethylene or poly-1-butene, and this component comprises about 25 to 50%, most preferably 45% by weight. The third component susceptible to high frequencies is preferably a dimeric fatty acid-based polyamide (for the purposes of the invention the corresponding hydrogenated derivatives are included in this term), and this component constitutes about 5 to 40%, most preferably 10% by weight, fourth component, i.e. . compatibilizing polymer, may be selected from the group consisting of various block copolymers of styrene with dienes or alpha-olefins, these compatibilizing polymers being optionally modified with smaller proportions of chemically reactive functional groups. An example of a compatibilizing polymer is styrene-ethylene-butene-styrene block copolymer (SEBS). the fourth component should comprise 5 to 40% and most preferably 10% by weight.

These three-component and four-component materials can be compounded and extruded into thin films that are sensitive to high-frequency oscillations, so that they can be welded by high-frequency heating. These films and tubes can be used, for example, for the production of sterile packages for fluids, blood reservoirs and blood components, intravenous and medicinal solutions, nutritional and respiratory care products, as well as dialysis solutions. These materials can also be used for the production of inlet pipes and access devices for tanks. The composition according to the invention can also be used for the production of other articles by injection molding, blow molding, thermoforming or other thermoplastic processing processes.

The compositions according to the invention are suitable for medical applications, since the film-forming components are minimally extractable by liquids and other constituents with which they come into contact. In addition, these films are environmentally friendly because they do not produce harmful degradation components when burned. Finally, these films represent an affordable alternative to polyvinyl chloride.

Other features and advantages of the present invention are described or will be apparent from the following more detailed description of the presently preferred embodiments of the invention.

Preferred embodiments of the invention are provided in this specification as illustrative examples and it is to be understood that the invention is not limited thereto. The invention can be implemented in various ways, all of which fall within the scope of protection.

More particularly, the invention is directed to materials that can be thermoplastically processed into articles, equipment, and articles that meet the above requirements.

As mentioned above, materials meeting these requirements can be made as compositions preferably containing three, four or more components. Three-component and four-component materials are discussed separately below.

Three-component materials

In the first embodiment of the three-component system, the first component serves to impart heat resistance and flexibility to the mass. This component may be selected from the group consisting of amorphous poly-alpha-olefins and is preferably a flexible polyolefin. These polyolefins should be dimensionally stable at high temperatures up to 121 ° C^EC, should have a melting point peak higher than 130 ° C and should be highly flexible, i.e. their modulus should not be higher than 137 MPa. Such a flexible polyolefin is commercially available under the name Rexene FPO 90007. This product has a melting point peak of 145 ° C and a modulus of 76 MPa. In addition, certain polypropylenes with high syndiotacticity also have such properties, i.e. high melting point and low modulus. The first component should comprise 40 to 90% by weight of the total polymer mass.

The second component of the three-component mass is a polymer susceptible to high-frequency oscillations, which imparts weldability to the mass by high-frequency heating. This component can be selected from one of two groups of polar polymers. The first group consists of copolymers of ethylene containing 50 to 85% ethylene, the remainder being comonomer units selected from the group consisting of acrylic acid, methacrylic acid, ester derivatives of acrylic acid with alcohols containing 1 to 10 carbon atoms, ester derivatives of methacrylic acid with alcohols containing 1 to 10 carbon atoms, vinyl acetate and vinyl alcohol. The polymer susceptible to high frequency oscillations can also be selected from the second group, which consists of copolymers containing segments of polyurethane, polyester, urea, polyimide, polysulfones and polyamides. These functionalized segments may comprise 5 to 100% of a polymer susceptible to high frequency oscillations. The polymer susceptible to high frequency oscillations should constitute 5 to 50% by weight of the total mass. Copolymers of ethylene and methyl acrylate, in which methyl acrylate constitutes 15 to 25% by weight, are preferably used as components sensitive to high-frequency oscillations.

The last component of the ternary mass is a polymer that compatibilizes the first and second components. This compatibilizing polymer is selected from the group consisting of copolymers with styrene blocks, which polymers are preferably functionalized with maleic anhydride. The third component should constitute 5 to 30% by weight of the total mass.

In a second embodiment of the three-component film, the first component is a component that imparts weldability to the mass by high frequency heating and flexibility in a desired temperature range. This first component gives the mass high temperature resistance (hence the name heat resistant polymer for its designation) and is selected from the group consisting of polyamides, polyimides, polyurethanes, polypropylene and polymethylpentene. The first component preferably constitutes 30 to 60% by weight of the total mass and is preferably polypropylene. The second component gives the mass weldability by high frequency heating and flexibility in the required temperature range. The polymer susceptible to high frequency oscillations is selected from the first and second groups mentioned above, except that no copolymer of ethylene with vinyl alcohol is used. The second component should constitute 30 to 60% by weight of the total mass. The third component provides compatibility between the first and second components and is selected from the group of block copolymers of the SEBS type. Preferably, the third component is functionalized with maleic anhydride. The third component should constitute 5 to 30% by weight of the total mass.

Four-component materials

The first component of the four-component mass imparts heat resistance to the film. This component may be selected from the group consisting of polyolefins, most preferably polypropylenes and more specifically a random copolymer of propylene with alpha-olefin (PPE). Suitable PPEs will preferably have a narrow molecular weight distribution. PPEs show the required stiffness and collapse resistance at autoclave temperatures of up to 121 ° C. However, in themselves, PPEs are too rigid to meet the flexibility requirements. However, when combined in the form of an alloy with certain low modulus polymers, masses with good flexibility can be formed. Examples of suitable PPEs are those commercially available under the names Soltex 4208 and Exxon Escorene PD9272.

These low modulus copolymers include ethylene-based copolymers, such as ethylene-vinyl12 acetate (EVA) copolymers, ethylene-alpha-olefin copolymers, and also so-called ultra-low density polyethylenes (ULDPE), which are usually less than 900 kg / m 2³. Polyethylenes of the ULDPE type include commercially available products sold under the trade name TAFMEr (^r) (Mitsui Petrochemical Co.) under the designation A485, Exact®^R^ (Exxon Chemical Co.) with designation 4023-4024 and construction polymers (Technology Polymers) Insite (^R) (Dow Chemical Co.). Suitable copolymers include poly-1-butene (PB), such as those sold by Shell Chemical Co. under the designations PB-8010 and PB-8310; thermoplastic elastomers based on block copolymers of the SEBS type (Shell Chemical Co.), polyisobutene (PIB) under the trade names Vistanex L-80, L-100, L-120 and L-140 (Exxon Chemical Co.), copolymers of ethylene with alkyl acrylate and copolymers of ethylene with methyl acrylate (EMA), such as those commercially available under the names EMAC 2707 and DS-1130 (Chevron) and copolymers of ethylene with n-butyl acrylate (ENBA) (Quantum Chemical). Copolymers of ethylene, for example with acrylic or methacrylic acid, and their corresponding neutralized salts and ionomers, such as PRIMACOr (^r) (Dow Chemical Co.) and SURYLN®^R^ (Ε. I. DuPont de Nemours &amp; Company). Ethylene-based copolymers typically have a melting point of less than about 110 ° C and are not suitable for autoclave applications. In addition, as shown below in some examples (as in Example 8G), not all alloy-forming pairs provide an optically clear material that meets the requirement for visual inspection. In addition, only a limited range of proportions of the individual components allows the requirements for flexibility and processability in the autoclave to be met at the same time.

The first component is preferably selected from the group consisting of homopolymers and random copolymers of propylene with alpha-olefins, which make up about 30 to 60, preferably 35 to 45, and most preferably 45% of the mixture. Thus, for example, a first component consisting of a random copolymer of propylene and ethylene is preferred, in which the ethylene content is in the range from 0 to 6 and preferably from 2 to 4% by weight, based on the weight of the polymer.

The second component of the four-component mass gives the mass flexibility and ductility at low temperatures. This component consists of a second polyolefin, which differs from the polyolefin of the first component in that it does not contain any propylene repeating units. Therefore, this polyolefin is called a non-propylene-based polyolefin. Preferably it is an ethylene copolymer such as ULDPE, polybutene, butene-ethylene copolymer, ethylene-vinyl acetate copolymer (vinyl acetate content in such copolymers is in the range of about 18 to 50%), ethylene-methyl acrylate copolymer (methyl acrylate content in such copolymers is approximately between 20 and 40%), a copolymer of ethylene with n-butyl acrylate (the content of n-butyl acrylate in such copolymers is in the range of about 20 to 40%) and a copolymer of ethylene with acrylic acid (the content of acrylic acid in such copolymers is greater than about 15%). Examples of such products are those sold under the names Tafmer A-4085 (Mitsui), EMAC DS-1130 (Chevron), Exact 4023, 4024 and 4028 (Exxon). Particularly preferred is a second component selected from the group consisting of ULDPE sold by Mitsui Petrochemical Company under the name Tafmer A-4085 and poly-1-butene, which is commercially available under the names PB8010 and PB8310 (Shell Chemical Co.), this polymer should be about 25 to 50% by weight, preferably 35 to 45 and most preferably 45% by weight.

In order to impart a dielectric loss when exposed to high-frequency oscillations, certain known additives with a high dielectric loss value (so-called polymers susceptible to high-frequency oscillations or RF-susceptible polymers) are added to the four-component mass. These polymers can be selected from the group comprising the polymers susceptible to the high frequency oscillations listed in the first or second group of substances characterized above.

Other RF-active materials include polyvinyl chloride, vinylidene chlorides, fluorides, a copolymer of bisphenol-A and epichlorohydrin, known as Phenoxys (^R) (Union Carbide). However, the high content of such chlorine- and fluorine-containing polymers makes the mass environmentally unsuitable, since the combustion of such a mass would produce inorganic acids.

The polyamides forming the polymer susceptible to high frequency oscillations are preferably selected from the group consisting of aliphatic polyamides formed by condensation of diamines having 2 to 13 carbon atoms, aliphatic polyamides formed by condensation of dicarboxylic acids having 2 to 13 carbon atoms, polyamides formed by condensation of dimeric fatty acids and copolymers containing amide groups. the latter copolymers can be random, block or grafted.

Polyamides, such as nylons, are widely used in thin film materials because they provide abrasion resistance to the film. However, nylon is rarely present in the layer in contact with the medicinal solution, as it usually causes contamination by leaching impurities into the solution. However, in the context of the invention, it has been found that the most suitable polymer susceptible to high frequency oscillations is a polyamide based on various dimerized fatty acids, marketed by Henkel Corporation under the names Macromeld and Versamid. These polyamides do not cause the above contamination. The polymer susceptible to high frequency oscillations should represent by weight about 5 to 30, preferably 7 to 13 and most preferably 10% of the total weight.

The fourth component gives the mass compatibility between the polar and non-polar components of the mass (hence it is sometimes referred to as a compatibilizing polymer). Preferably, it is a styrene block copolymer with soft hydrocarbon segments. Preferably, the fourth component is selected from the group consisting of block copolymers of the SEBS type which are modified with maleic anhydride, epoxide or carboxylate functional groups. Particularly preferred is a block copolymer of SEBS containing maleic anhydride functional groups (so-called functionalized polymer). This product is commercially available under the name Kraton RP-6509 (Shell Chemical Company). The compatibilizing polymer should comprise about 5 to 40, preferably 7 to 13 and most preferably 10% by weight of the total weight.

It may also be desirable to add a fifth component, consisting of a non-functionalized block copolymer of the SEBS type, such as the copolymer sold by Shell Chemical Company under the names Kraton G-1652 and G-1657. The fifth component should be at most about 5 to 40, preferably 7 to 13% by weight of the total weight.

Trace amounts of other additives, such as glidants, lubricants, waxes and anti-blocking agents, may be added to all of the compositions described above as needed in accordance with known practice in the art, as long as the resulting composition meets the physical requirements defined above.

The above-mentioned multicomponent compositions can be processed into various products, such as films. Films can be made with several different technologies that are well known in the industry. For example, the individual components can be mixed in dry form in a high performance mixer such as a Welex mixer and then fed to an extruder. The components can also be metered gravimetrically into a high-performance twin-screw mixing extruder, such as a Werner-Pfleiderer mixer. The material leaving this machine can be cooled in a water bath in the form of a multiple bundle, pelletized and dried for further use. The pelletization step can be avoided in a third alternative, in which the material exiting the compounding extruder is fed directly to the extruder to produce an extruded film. It is also possible to incorporate a high-intensity mixing section into the film extruder, in which case the alloy film can be produced in a single extruder. The resulting alloy can be processed into other products and shapes using other thermoplastic processing machines, such as injection or injection molding machines. Of course, there are a number of other known processes for processing alloys into films, and the present invention is not limited to the production of films by the above methods, which have been given by way of illustrative example only.

Masses containing different components in different percentages, which are given in the following examples, were processed into films and tested by the following test methods:

(1) Autoclavable workability

The resistance to autoclaving is measured by the flow of the sample, i.e. as an elongation of the sample at 121 ° C per hour at a load of 185 kPa. The resistance to autoclaving must be 40% or less. The results of this test are given in the following tables in the column marked Autokl.

(2) Elongation at low temperatures and at ambient temperature (A) Elongation at low temperatures

The test is performed in an impact measuring device equipped with a low-temperature chamber cooled by liquid nitrogen. A film sample measuring about 18 x 18 cm is mounted on a circular sample holder about 15 cm in diameter. A hemispherical impact head equipped with voltage sensors is driven at high speed (usually about 3 m / s) onto a pre-conditioned film sample that strikes in the middle.

The dependence of the deformation on the stress is plotted in the graph and the impact energy is calculated by integration. The temperature at which the impact energy increases dramatically and the brittle fracture of the sample disappears due to the sample becoming ductile and undergoing high deformation is considered a measure of the ductility of the film at low temperatures. The results of this test are given in the following tables in the column marked Temp. L.

(B) Mechanical module and recovery

A film sample processed in an autoclave of known geometry is mounted in a servohydraulically driven mechanical crosshead tester. In this device, the film sample elongates at a crosshead speed of 25 cm / min up to about 20% elongation. At this point, the crossheads move and then return in the direction opposite to the direction of the original stretching of the sample. The dependence of the deformation on the stress is recorded using a digital recording device.

The modulus of elasticity in the tables, denoted E (MPa), is determined from the initial direction of the strain curve and the recovery is determined by measuring the permanent elongation. Recovery is expressed as a percentage of sample elongation.

(3) Weldability by high frequency heating

A Callahan 27.12 MHz, 2 kW Radio Frequency Generator is used for this test, to which is connected a rectangular jaw measuring approximately 6.3 x 10 cm located opposite a flat brass electrode, which is also connected to the generator. After clamping the two sheets of test material in the jaw, high frequency energy of different amplitude and duration is applied. After the high-frequency cycle, the jaw is opened and the resulting weld is tested by manually tearing the leaves apart. The strength of the joint (against the strength of the film) and the method of failure (peeling, tearing or cohesive failure) are used to evaluate the weldability of the material by high-frequency heating.

Alternatively, the test film is first spray coated with gold or palladium at a thickness of 10 nm to make the surface conductive, a circular sample is cut from the film, and fixed between the parallel electrodes of the cell to measure the dielectric capacitance. The dielectric constant and dielectric loss are then measured at various frequencies up to 10 MHz and temperatures up to 150 ° C using a Hewlett Packard 4092 automatic high frequency bridge. Dielectric loss makes it possible to calculate the development of heat in a high-frequency field. From calculations and correlations with high-frequency welding experiments, the minimum dielectric loss to achieve weldability is determined.

If the high-frequency weldability is determined using a Callahan tester, the following classification scale shall be used:

High-frequency High-frequency time - Strength The degree of energy processing of a joint

<td> 80</td><td> %</td><td> 10</td><td>is not</td><td> 0</td>

peel off. = separable by peeling

The results of this test are shown in the following tables in the column labeled RF.

(4) Optical clarity

A 5 x 5 cm square is cut from a sample of autoclaved film, placed in a Hunter colorimeter, and its internal haze is measured according to ASTM D-1003. Generally, an internal haze value of less than 30%, preferably less than 20%, is required at these thicknesses (in the following tables, this value is given in the column labeled Turbidity (%)).

(5) Deformation bleaching

The autoclaved film is stretched at a mean head speed of about 50 cm / min to about 100% elongation (twice the original length) and the presence (symbol 1) or absence (symbol 0) of deformation bleaching is recorded. In the tables, this value is indicated by the abbreviation Def white.

(6) Ecological compatibility

Ecological compatibility includes three important properties: a) the material must not contain low molecular weight plasticizers that could be leached after landfilling, b) the material should be thermoplastically recyclable to useful items after fulfilling its primary task in medical application and c) if the material is disposed of by incineration in order to regenerate energy, which should not release more harmful inorganic acids into the environment. In summary, ecological compatibility is characterized in the tables below in the column marked Ekol. The mass should also contain less than 0.1% by weight of halogens. To facilitate recycling by melt processing, the resulting mass should have a loss tangent value higher than 1.0 at 1 Hz and at processing temperatures.

(7) Compatibility with solutions

By solution compatibility is meant that the solution in contact with the film is not contaminated with the components contained in the mass. In the following tables, the compatibility with the solutions is indicated in the column marked Comp.r. The proportion of low molecular weight water-soluble substances contained in the mass should be less than 0.1%.

In the following exemplary embodiments, the three-component to five-component compositions according to the invention and the results obtained in their testing are characterized. These examples demonstrate certain unexpected benefits that will be obtained using these materials. The examples are purely illustrative and do not limit the scope of the invention in any way.
