THERMOPLASTIC ACRYLIC RESIN COMPOSITION

摘要

A Novel acrylic thermoplastic r sin composition transparent and excellent in flexibility consisting of from 1 through 99 parts by weight of at least one multi-layer structure polymer ¢I! and from 99 through 1 part by weight of at least one multi-layer structure polymer ¢II!, said polymer ¢I! and polymer ¢II! having the following structures: Multi-layer structure polymer ¢I!: A multilayer structure polymer comprising the following (A) and (B): (A) an inner layer polymer (A) constituted of from 60 through 100 parts by weight of an alkyl acrylate having C1-C8 alkyl group (A1), from 0 through 40 parts by weight of a monomer having copolymerizable double bond (A2), from 0 through 10 parts by weight of a polyfunctional monomer (A3) and from 0.1 through 5 parts by weight, per 100 parts by weight of the sum of (A1) to (A3), of a grafting agent, wherein gel content of said inner layer polymer (A) is 60% by weight or higher and its proportion to said polymer ¢I! is from 5% by weight through 46% by weight; (B) an outer layer polymer (B) constituted of from 60 through 100 parts by weight of an alkyl methacrylate having C1-C4 alkyl group (B1) and from 0 through 40 parts by weight of a monomer having copolymerizable double bond (B2), wherein the proportion of said outer layer polymer (B) to said polymer ¢I! is from 54% by
