AROMATIC POLYCARBONATE-STYRENE POLYMER RESIN COMPOSITION

摘要

An aromatic polycarbonate-styrene polymer resin composition comprising (A) an aromatic polycarbonate, (B) a specified rubber-modified styrene polymer, and (C) a compatibilizer comprising a copolymer of aromatic vinyl monomers wherein the distribution of the proportions of the comonomer components is so heterogeneous that the copolymer is composed of copolymer molecules having different solubility parameter (SP) values, that the difference in SP value between the copolymer molecule having the largest SP value and the copolymer molecule having the smallest SP value is 0.3-1.0 [(cal/cm<3>)<0.5>], and that the average SP value of the copolymer is 10.6-11.0 [(cal/cm<3>)<0.5>]. The composition has not only high impact and heat resistances but also high melt fluidity and is useful in the fields of household electric components and OA equipment components.
