Claims
- 1. 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.
- 2. A polyarylene sulfide resin composition according to claim 1, wherein the polyarylene sulfide resin is a polyphenylene sulfide resin.
- 3. A polyarylene sulfide resin composition according to claim 1, wherein the organic silane compound having an epoxy group is one or more of those which are represented by the formula, ##STR8## wherein m represents an integer of 1 to 3, R.sup.3 represents a single bond or an alkylene group having 1 to 3 carbon atoms, R.sup.4 represents a methyl or ethyl group and Y and Z represent groups selected from the following respective groups, ##STR9## Z; --OR.sup.4, --OCOR.sup.4 or --Cl in which R.sup.5 represents an alkylene group having 1 to 3 carbon atoms, and R.sup.4 is as defined above provided that when Y represents a glycidyl group or a 3,4-epoxycyclohexyl group, R.sup.3 represents a single bond or an alkylene group having 1 to 5 carbon atoms.
- 4. A polyarylene sulfide resin composition according to claim 3, wherein the organic silane compound having an epoxy group is one or more members selected from the group consisting of (3-glycidyloxypropyl)trimethoxysilane, (3-glycidyloxypropyl)methyldiethoxysilane and 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane.
- 5. A polyarylene sulfide resin composition according to claim 1, wherein the polyorganosiloxane rubber component constituting the compound rubber used in the polyorganosiloxane graft copolymer has a repeating unit of dimethylsiloxane.
- 6. A polyarylene sulfide resin composition according to claim 1, wherein the polyalkyl (meth)acrylate rubber component constituting the compound rubber used in the polyorganosiloxane graft copolymer has a repeating unit of polybutyl acrylate.
- 7. A polyarylene sulfide resin composition according to claim 1, containing a filler as an additional component in an amount of 10 to 300 wt. % based on the total amount of the components A, B and C.
- 8. A polyarylene sulfide resin composition according to claim 7, wherein the filler is selected from glass fibers, carbon fibers or a mixture thereof.
