ABSTRACT:
A polycarbonate resin composition is given as a mixture of (A) 97-50 wt. % of a polycarbonate resin, and (B) 3-50 wt. % of a graft copolymer. The graft copolymer is obtained by graft-polymerizing 50-95 wt. parts of a monomer selected from (b1) a monomer mixture comprising 60-90 wt. % of an aromatic vinyl monomer, 40-10 wt. % of a vinyl cyanide monomer, and 0-30 wt. % of a monomer copolymerizable with the monomers and (b2) an alkyl methacrylate having an alkyl group including 1-4 carbon atoms in the presence of a latex containing 5-50 wt. parts of a rubber polymer with respect to the total of the monomer and the rubber polymer as 100 wt. parts. The graft copolymer includes a graft-polymerized component having a weight-average molecular weight 50.times.10.sup.4 -300.times.10.sup.4. The polycarbonate resin composition shows a good extrudability and provides a sheet product which exhibits good thermoforming characteristics, such as suppressed drawdown and good deep drawability.
