配管用成型品
摘要：
本发明涉及配管用成型品，其目的在于提供一种不含丁二烯且外观、耐冲击性、耐热性优异的配管用成型品。本发明的配管用成型品是由含有(A)聚苯醚、(B)聚苯乙烯均聚物以及(C)下述氢化嵌段共聚物的树脂组合物形成的配管用成型品，该氢化嵌段共聚物是将含有苯乙烯聚合物嵌段和共轭二烯化合物聚合物嵌段的嵌段共聚物氢化而得到的、重均分子量为10万～40万的范围的氢化嵌段共聚物，该配管用成型品的特征在于，在所述树脂组合物中，相对于所述(A)、(B)以及(C)成分的总量100质量份，含有所述(A)成分5质量份～50质量份、所述(B)成分20质量份～90质量份、以及所述(C)成分3质量份～30质量份，所述树脂组合物中的丁二烯小于0.1mg/kg。
摘要（英）：

To provide a molded article for piping which is free of butadiene and has excellent appearance, impact resistance and heat resistance. There is provided a molded article for piping composed of a resin composition containing a hydrogenated block copolymer having a weight average molecular weight of 100000-400000 which is obtained by hydrogenation of a block copolymer composed of (A) a polyphenylene ether, (B) a polystyrene homopolymer, (C) a styrene polymer block and a conjugated diene compound polymer block, wherein the resin composition comprises 5-50 pts.mass of the component (A), 20-90 pts.mass of the component (B) and 3-30 pts.mass of the component (C) based on the total 100 pts.mass of the components (A), (B) and (C), and the content of the butadiene in the resin composition is less than 0.1 mg/kg.
