POLYMER COMPOSITION AND MOLDINGS THEREOF |
摘要 |
<p>[PROBLEMS] To provide a polymer composition that simultaneously has excellent paintability and high oil resistance and is also excellent in thin-wall moldability and flexibility; and a molded article produced by injection-molding of the composition and being suitable for composite-molded grips, automotive interior and exterior trims, and so on. [MEANS FOR SOLVING PROBLEMS] A polymer composition and a molded article that are comprising 33 to 67% by mass of a polybutylene terephthalate-based resin (A) and 67 to 33% by mass of an acrylic block copolymer (B); and in the acrylic block copolymer (B), two polymer blocks (b2) comprising a unit of methacrylic ester such as methyl methacrylate are bonded to the both ends of a polymer block (b1) comprising a unit of acrylic ester such as butyl acrylate, the total mass of the polymer block (b2) is 20 to 35% by mass with respect to the acrylic block copolymer (B), the weight-average molecular weight is 50000 to 100000, and the order-disorder transition temperature is 180 to 230°C.</p> |
