Dentistry material

The present invention relates to the use of groups of vinyl containing polyurethane resins such as stamping materials primarily for dentistry.

By imprinting materials we mean masses which have been transformed by a hardening process from a brittle state, to a hard and elastic one. For this purpose, masses are preferred which can harden and acquire elastic rigidity.

* & manufacture of rubber products is achieved in various ways. In addition to the saturation of unsaturated hydrocarbons but one or more double bonds, it leads, t?. 'X. and hardening of thioplasts, which is achieved by the reaction of aqueous solutions of alkali multiply sulfides with aliphatic dhalogens as derivatives with elastic properties. Further similar derivatives are obtained by silica polycondensation. Yet another group of rubber derivatives can be produced by the polyprosthetic reaction of a polyester or plyether ether with a diisocyanate having thio adhesives before and after crosslinking and an unpleasant odor. For polyurethanes there is doubt from a cryptological point of view, they do not contain free isocyanate groups. * On the other hand, all these masses present a relatively high contraction contraction which we are trying to offset, (By adding, in a large, proportion of filling materials. .

Although these products are characterized by a relatively limited shrinkage, polymerization has major drawbacks; in water storage there are significant changes in Scottish processes. Apart from that, there is also a hesitation on the part of the Armenians, because they are divided by groups of aristocrats.

Some arizidines are known as carcinogenic bumps.

* All Imprinters used in ophthalmology have. time constraints on both processing and curing. After formulation, without reacting the mixture, there is usually an available processing time of about 3 *. * The hardening time that follows does not usually exceed about 5 *.

So it came as a surprise that polyurethane resins contained vinyl groups. they can harden. cold, within what time limits the action has set, in rubber tires — coyote masses, and that these masses do not present in their use as striking the above-mentioned disadvantages. It is therefore an object of the invention to use conversion products from

(c) unsaturated monodroxide compounds and preferably derivatives of 5 acrylic and / or metacrylic beads containing droxyl groups, which are transported in the process of netting, as material Imprints, mainly for dentistry.

During the preparation of the useful compounds according to the Effects of the masses, the diodrode fibrosis can be mixed with the dioxyalkyl ester of acrylics and f, or the methacrylic ester, and no active action is taken. As a rule, it is such a one-way reaction in which first the quantities of the unsaturated alkaline ester and the bisubyanate are reacted with the same molecule, and then this inhibitor is converted to the inhibitor.
