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/cm3)0.5], and that the average SP value of the copolymer is 10.6-11.0 [(cal/cm3)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.
一种芳香族聚碳酸酯-苯乙烯聚合物树脂组合物,包括(A)芳香族聚碳酸酯,(B)特定橡胶改性苯乙烯聚合物,和(C)由芳香族乙烯基单体共聚物组成的相容剂,其中共聚单体组分的比例分布非常不均匀,共聚物由具有不同溶解度参数(SP)值的共聚物分子组成,具有最大 SP 值的共聚物分子与具有最小 SP 值的共聚物分子之间的 SP 值差为 0.3-1.0 [(cal/cm3)0.5] ,共聚物的平均 SP 值为 10.6-11.0 [(cal/cm3)0.5] 。3-1.0 [(cal/cm3)0.5] ,共聚物的平均 SP 值为 10.6-11.0 [(cal/cm3)0.5] 。该组合物不仅具有较高的抗冲击性和耐热性,还具有较高的熔体流动性,可用于家用电气元件和 OA 设备元件领域。
