POLYBUTYLENE TEREPHTHALATE RESIN COMPOSITION AND MOLDING

摘要

Provided is a polybutylene terephthalate resin composition having performance such as high durability in hot/cold cycle environments along with high strength.  In (A) 100 parts by weight of polybutylene terephthalate resin having not more than 30 meq/kg of terminal carboxyl groups, there are compounded: (B) carbodiimide compound in an amount of 0.3 to 1.5 equivalents of carbodiimide functional group per terminal carboxyl group of the polybutylene terephthalate resin (A), (C) 20 to 100 parts by weight of fibrous filler, and (D) 5 to 15 parts by weight of elastomer.
