The composition of styrene acrylate - - acrylonitrile, endowed of resistance to temperature high thermochromism

摘要

An acrylate-aromatic vinyl-vinyl cyanide resin composition having thermochromic resistance at high temperatures is provided. The resin composition includes: (A) about 20 to about 50% by weight of acrylic graft copolymer; (B) about 20 to about 50% by weight of two types of aromatic vinyl-vinyl cyanide copolymers with different molecular weights; and (C) about 30 to about 50% by weight of alpha-methyl styrene terpolymer.
