Abstract
Abstract The invention provides a novel resin composition based on a polyphenylenesulfide resin which can be molded into shaped articles imparted with remarkably improved impact strength, cracking resistance and heat shock resistance. The inventive resin composition comprises 100 parts by weight of a polyphenylenesulfide resin, from 10 to 300 parts by weight of an inorganic filler and from 1 to 100 parts by weight of a fluorine-containing rubber such as a copolymer of vinylidene fluoride and hexafluoropropylene having specified Mooney viscosity.
