Title: POLYCARBONATE RESIN COMPOSITION AND METHOD FOR PRODUCING SAME
Abstract:
Provided are: a polycarbonate resin composition which has excellent mechanical properties and wet heat resistance, while being free from the problem of mold contamination due to mold deposit; and a production method which is capable of producing this polycarbonate resin composition with high productivity. A polycarbonate resin composition which contains 60-95% by mass of a polycarbonate resin (A) and 40-5% by mass of an emulsion polymerized styrene resin (B) based on 100% by mass of the total of the components (A) and (B), and which is characterized in that: the emulsion polymerized styrene resin (B) is a graft copolymer that is obtained from a styrene monomer-vinyl cyanide monomer and/or an alkyl (meth)acrylate monomer-rubbery polymer; and the total amount of gas in cases where the resin composition is heated at 280°C for 10 minutes is 3,000 ppm or less in terms of the mass of decane.
