基于聚碳酸酯，ASA和乙烯基芳烃/含有共聚物的热塑性成型材料

Thermoplastic molding material based on polycarbonate, ASA and vinylaromatics/an-containing copolymers
摘要：
A thermoplastic molding material containing, based on components A, B and C,A from 10 to 90% by weight of one or more polycarbonates,B from 10 to 50% by weight of one or more graft copolymers,C from 10 to 50% by weight of one or more thermoplastic copolymers containing a vinylaromatic monomer of 8 to 12 carbon atoms and acrylonitrile,wherein component B is composed ofB.sub.1 a first, coarsely divided graft copolymer which has an average particle size of from 200 to 700 nm (d.sub.50 value of cumulative molecular weight distribution) in a proportion of from 30 to 70% by weight, based on B, andB.sub.2 a second, finely divided graft copolymer which has an average particle size of from 50 to 180 nm (d.sub.50 value of cumulative molecular weight distribution) in a proportion of from 70 to 30% by weight, based on B,is used for producing moldings.
摘要（中）：

一种热塑性模塑材料，其基于组分A，B和C，A为10至90重量％的一种或多种聚碳酸酯，B为10至50重量％的一种或多种接枝共聚物，C为10至50％ 的一种或多种含有8-12个碳原子的乙烯基芳族单体和丙烯腈的热塑性共聚物，其中组分B由B1组成，第一种粗分离的接枝共聚物的平均粒度为200-700nm（d50值 的累积分子量分布），基于B和30的比例为30〜70重量％，B2为平均粒径为50〜180nm的第二微细接枝共聚物（d50累积分子量值 分布）以按重量计70％至30％的比例用于生产模制品。
