Abstract
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.
Claims8
A polyarylene sulfide resin composition obtained by melt-mixing a composition consisting essentially of
- 60 to 99 parts by weight of a polyarylene sulfide resin (component A),
- 1 to 40 parts by weight of a polyorganosiloxane graft copolymer (component B) obtained by graft-polymerizing one or more kinds of vinyl monomer onto a compound rubber of 0.08 to 0.6 .mu.m in average particle size consisting of a polyorganosiloxane rubber component and a polyalkyl (meth)acrylate rubber component and having such a structure that 1 to 99 wt. % of the polyorganosiloxane rubber component and 1 to 99 wt. % of the polyalkyl (meth)acrylate rubber component have been inseparably united with each other, the total amount of the components A and B being 100 parts by weight, and
- an organic silane compound having an epoxy group (component C) of 0.01 to 10 parts by weight based on 100 parts by weight of the total amount of the components A and B.
