Patent ID: 8247478

Claim:
A thermoplastic resin composition containing 100 parts by weight of (A) a thermoplastic resin and from 0.5 to 20 parts by weight of (B) a graft copolymer, wherein: the graft copolymer (B) contains from 70% to 99% by weight of a crosslinked core (b2) prepared through polymerization of a monomer for the core (b2), containing 70% by weight or more of an acrylate, in the presence of from 0.5% to 20% by weight of a non-crosslinked seed (b1) having a weight-average molecular weight of 40,000 or less, and from 0.5% to 10% by weight of a shell (b3) prepared through polymerization of a monomer for the shell (b3) containing 50% by weight or more of a methacrylate, and the thermoplastic composition further contains from 0.01 to 3.0 parts by weight, relative to 100 parts by weight of the graft copolymer (B), of (C) a water-soluble polymer compound having the property of forming a physical gel.
