Polyarylene sulfide resin compositions

摘要

A polyarylene sulfide resin composition excellent in compatibility between a polyarylene sulfide resin and a polyorganosiloxane graft copolymer is obtained by melt-mixing a composition consisting essentially of 60 to 99 parts by weight of a polyarylene sulfide resin, to 40 parts by weight of a polyorganosiloxane graft copolymer which was obtained by graft-polymerizing one or more kinds of a vinyl monomer onto particles of a compound rubber consisting of a polyorganosiloxane rubber component and a polyalkyl (meth)acrylate rubber component inseparably united with each other, and 0.01 to 10 parts by weight of and organic silane compound having an epoxy group per 100 parts of the mixture.
