Aromatic polycarbonate-styrene polymer resin composition

摘要

Disclosed is an aromatic polycarbonate-styrene polymer resin composition comprising (A) an aromatic polycarbonate, (B) a specific rubber-modified styrene polymer and (C) a compatibility agent which is a copolymer containing an aromatic vinyl monomer and which has a non- uniform distribution with respect to the proportions of component monomers constituting the copolymer, so that the copolymer comprises copolymer molecules having different solubility parameter (SP) values, wherein the difference in SP value between the copolymer molecule having a maximum SP value and the copolymer molecule having a minimum SP value is from 0.4 to 0.6 (cal/cm.sup.3).sup.1/2, and wherein the copolymer has an average SP value of from 10.6 to 11.0 [(cal/cm.sup.3).sup.1/2 ]. The aromatic polycarbonate-styrene polymer resin composition of the present invention has not only a high impact resistance and a high heat resistance but also a high melt flowability, so that it is useful in various industrial fields, especially, fields of parts for household electrical appliances, parts for office automation machines, and the like.
