Patent ID: 7776966

Claim:
A thermoplastic resin composition excellent in mold release ability and slidability comprising 0.01 to 5% by weight of a polyorganosiloxane-containing graft copolymer (C) and 99.99 to 95% by weight of a thermoplastic resin (D), wherein the polyorganosiloxane-containing graft copolymer (C) is obtained by polymerizing 40 to 10 parts by weight of a vinyl monomer (B) in the presence of 60 to 90 parts by weight of a polyorganosiloxane (A) with a proviso that a sum of (A) and (B) is 100 parts by weight, a graft ratio of the polyorganosiloxane-containing graft copolymer (C) is less 0.5% or less, and a content of methyl ethyl ketone-insoluble matter in the polyorganosiloxane-containing graft copolymer (C) is 3% by weight or less.
