Soft thermoplastic resin composition

摘要

A soft thermoplastic resin composition comprising:;100 parts by weight of a resin component (A) containing 15 to 65 parts by weight of a vinyl chloride resin having a degree of polymerization of 2000 or less, and 35 to 85 parts by weight of a polyhydroxyalkanoate; and 0.1 to 8 parts by weight of a resin component (B) which is one or more resins selected from the group consisting of a (meth)acrylate resin and an acrylonitrile-styrene resin, and has a weight average molecular weight, in terms of the polystyrene, of 400,000 or more.

1. A soft thermoplastic resin composition comprising:
100 parts by weight of a resin component (A) comprising from 15 to 65 parts by weight of a vinyl chloride resin having a degree of polymerization of 2000 or less, and from 35 to 85 parts by weight of a polyhydroxyalkanoate; and from 0.1 to 8 parts by weight of a resin component (B) which is one or more resins selected from the group consisting of a (meth)acrylate resin and an acrylonitrile-styrene resin, and has a weight average molecular weight, in terms of polystyrene, of 400,000 or more, wherein the polyhydroxyalkanoate is copolymer comprising monomer units derived from 3-hydroxybutyrate and monomer units derived from hydroxyalkanoate other than 3-hydroxybutyrate, and the hydroxyalkanoate other than the 3-hydroxybutyrate is at least one member selected from the group consisting of 4-hydroxybutyrate, 3-hydroxyvalerate, 3-hydroxyhexanoate, 3-hydroxyoctanoate, and 3-hydroxydecanoate.
