聚芳硫醚系树脂组合物以及嵌入成型体
摘要：
本发明提供具备适于嵌入成型的流动性、且可以赋予其成型品更优异的高低温冲击特性的PAS系树脂组合物以及使用该树脂组合物得到的嵌入成型品。本发明的PAS系树脂组合物包含：具有末端羧基的聚芳硫醚树脂、烯烃系共聚物、玻璃纤维和碳酸钙。聚芳硫醚树脂的重均分子量为15000～40000，烯烃系共聚物包含α‑烯烃、α,β‑不饱和酸的缩水甘油酯和丙烯酸酯作为共聚成分，树脂组合物中的源自缩水甘油酯的共聚成分的含量为0.2～0.6质量％。此外，玻璃纤维的纤维直径为9～13μm，碳酸钙的平均粒径为10～50μm，树脂组合物中的玻璃纤维和碳酸钙的总含量为45～55质量％。
摘要（英）：

A PAS resin composition which has fluidity optimal for insert molding and which can impart superior high- and low-temperature impact resistance to a molded body, and an insert-molded body formed using said resin composition are provided. This PAS resin composition includes a polyarylene sulfide resin having a terminal carboxyl group, an olefin copolymer, glass fibers and calcium carbonate. The weight-average molecular weight of the polyarylene sulfide is 15000-40000; as copolymer components, the olefin copolymer includes alpha-olefins, glycidyl esters of alpha,beta-unsaturated acids, and acrylate esters, and the content of the copolymer component derived from the glycidyl esters in the resin composition is 0.2-0.6 mass%. Further, the fiber diameter of the glass fibers is 9-13[mu]m, the average particle diameter of the calcium carbonate is 10-50[mu]m, and the total content of glass fibers and calcium carbonate is 45-55 mass% of the resin composition.
