Claims
- 1. Graft copolymer particles obtained by graft-polymerizing one or more kinds of vinyl monomer onto a compound rubber comprising a polyorganosiloxane component and an alkyl (meth)acrylate rubber component, which graft copolymer particle has a number average particle size of 0.01 to 0.07 .mu.m, the volume of particles larger than 0.10 .mu.m being 2.3% to 20% of the whole particle volume.
- 2. Graft copolymer particles according to claim 1, wherein the volume of particles larger than 0.10 .mu.m is 2.3% to 10% or less of the whole particle volume.
- 3. Graft copolymer particles according to claim 1, wherein the number average particle size is 0.01 to 0.06 .mu.m, and the volume of particles larger than 0.10 .mu.m is 2.3% to 20% or less of the whole particle volume.
- 4. Graft copolymer particles according to claim 1, wherein the alkyl (meth)acrylate rubber component comprises alkyl (meth)acrylate and a polyfunctional alkyl(meth)acrylate.
- 5. A method for producing graft copolymer particles according to claim 1, wherein one or more kinds of vinyl monomer are graft-polymerized onto a compound rubber obtained by polymerizing an alkyl (meth)acrylate compound rubber obtained by polymerizing an alkyl (meth)acrylate component comprising alkyl (meth)acrylate and a polyfunctional alkyl (meth)acrylate with polyorganosiloxane particles having a number average particle size of 0.003 to 0.06 .mu.m, the volume of particles larger than 0.10 .mu.m being 2.3% to 20% of the whole particle volume.
- 6. A method for producing graft copolymer particles according to claim 5, wherein the polyorganosiloxane is obtained by emulsion-polymerizing an organosiloxane containing a dialkylorganosiloxane as a main component.
- 7. A thermoplastic resin composition comprising a graft copolymer (A) according to claim 1 and a thermoplastic resin (B) selected from the group consisting of polymers obtained by polymerizing one or more kinds of monomer selected from the group consisting of aromatic alkenyl compounds, methacrylates, acrylates and vinyl cyanide compounds; mixtures of a polyphenylene-ether resin and a polystyrene resin; polyacetal resins; vinyl chloride resins; polyester resins; polycarbonate resins; polyamide resins; polyphenylenesulfide resins and (co)polymers of an ethylenic unsaturated monomer.
