Claims
- 1. A polyarylene sulfide resin composition obtained by melt-mixing a mixture comprising
- (A) a polyarylene sulfide resin and
- (B) a polyorganosiloxane graft copolymer obtained by graft-polymerizing one or more kinds of vinyl monomer containing at least an epoxy group-containing vinyl monomer onto a compound rubber in which a polyorganosiloxane rubber and a polyalkyl (meth) acrylate rubber have been inseparably united with each other, wherein the proportion of said polyorganosiloxane graft copolymer derived from said one or more kinds of vinyl monomer is 5-50 wt. % based on a total weight of said polyorgano-siloxane graft copolymer.
- 2. A polyarylene sulfide resin composition according to claim 1, wherein said polyarylene sulfide resin is a polyphenylene sulfide resin.
- 3. A polyarylene sulfide resin composition according to claim 1, wherein said compound rubber is one obtained by polymerizing an alkyl (meth)acrylate, a crosslinking agent for a polyalkyl (meth)acrylate rubber and a graft-linking agent for a polyalkyl (meth)acrylate rubber in the presence of a polyorganosiloxane rubber obtained by emulsion-polymerizing organosiloxane, a crosslinking agent for a polyorganosiloxane rubber and, optionally, a graft-linking agent for a polyorganosiloxane rubber.
- 4. A polyarylene sulfide resin composition according to claim 1, wherein the proportion of said polyorganosiloxane graft copolymer derived from said epoxy group-containing vinyl monomer is 1 to 40 wt. % based on the total weight of said polyorganosiloxane graft copolymer.
- 5. A polyarylene sulfide resin composition according to claim 1, wherein said polyorganosiloxane graft copolymer has an average particle size of 0.08 to 0.6 .mu.m.
- 6. A polyarylene sulfide resin composition according to claim 1, wherein the amount of the polyorganosiloxane graft copolymer is 1-70 parts by weight per 100 parts by weight of the polyarylene sulfide resin.
- 7. A polyarylene sulfide resin composition according to claim 1 which contains 10 to 300 parts by weight of a filler per 100 parts by weight of the total amount of the resin components comprising as main resins the polyarylene sulfide resin (A) and the polyorganosiloxane graft copolymer (B).
- 8. A polyarylene sulfide resin composition according to claim 1, wherein the proportion of said polyorganosiloxane graft copolymer derived from said epoxy group-containing vinyl monomer is 5-30 wt. % based on the total weight of said polyorganosiloxane graft copolymer.
