Absorbent articles comprising biodegradable polyester blend compositions

Abstract

The invention involves having the toughness and ductility, blends of biodegradable aliphatic polyester composition and method of preparation of such combinations. The invention involves products made from such blends, including but not limited to films, fibres, non-woven fabrics, sheets, paint, adhesives, foam and molded products for packaging. These products demonstrate the ideal combination of high strength, ductility and toughness, while maintaining the flexibility and availability of biodegradable and compostable. The invention also involving absorption products (such as diapers, sanitary napkins, pads, etc), absorption products mentioned include a can of liquid surface, not through the liquid polyester blends, including the invention of the composition for the film by lining the back and located between the surface and backing layers absorbing core. This invention of polyester total mixed property including: (a) including two species no Board repeat monomer unit of copolymer property, which first species no Board repeat monomer unit has right type structure: type in the R1 is h, or C1-C2 alkyl, and n is 1 or 2; second species no Board repeat monomer unit including at least a selected since type (II) and type (III) of monomer: type in the R2 is C3-C19 alkyl or C3-C19 chain Ene base, and (III) which m for 2 to about 16; which at least about 50% Moore copolymers include (I) random structure of repeating monomer units of the first random repeating monomer units. And poly-chain alkyl acid content of poly-chain alkyl esters and fatty ester, polymer with 20% weight total weight at least about. See right type (I) which R1 is h or C1-2 alkyl, and n is 1 or 2; and second species no Board repeat monomer unit has Xia type structure: see right type (ii) which R2 is C3-19 alkyl or chain Ene base, and (b) fat family ester class polycondensation property, the polycondensation property by fat family multi alcohol and fat family more carboxylic acid compounds synthesis.
