Polymer blends of polycarbonate, styrene terpolymer and abs resin

摘要

Polymer blend compositions comprise polycarbonate, styrene-acrylonitrile-maleic anhydride terpolymer and ABS resin. The ABS resin is included in the blends in amounts less than 20 weight percent and contains at least 40 weight percent of a diene rubber substrate. The blends exhibit high heat deflection temperatures and good impact strength and modulus.
