Patent ID: 8729205

Claim:
A thermoplastic resin composition provided by mixing 0.1 to 30 parts by mass of a flowability improver for engineering plastics with 100 parts by mass of an engineering plastic (B), wherein the flowability improver for engineering plastics comprises a polymer (A) comprising 50 to 93% by mass of aromatic vinyl monomer unit (a1), 7 to 50% by mass of phenyl(meth)acrylate monomer unit (a2), and 0 to 40% by mass of other monomer unit (a3) (a total of the units (a1) to (a3) is 100% by mass), wherein polymer (A) has a weight average molecular weight of 30000 to 100000 wherein the engineering plastics (B) is a polycarbonate resin, and, wherein the polymer (A) is obtained by suspension polymerization or emulsion polymerization.
