Abstract:
1. The thermoplastic composition containing: 70 to 99% by mass of thermoplastic resin (A1) containing a polycarbonate resin as an essential component; and 1 to 30% by mass of graft copolymer (B) which is a graft copolymer obtained by emulsion graft polymerization of a monomer or monomer mixture containing at least alkyl methacrylate in the presence of a latex containing a butadiene rubber polymer, wherein the amount of said butadiene rubber polymer included is in the range of 55 to 90% by mass, and said graft copolymer (B) is obtained by using 0.05 to 10 parts by mass of disodium alkylphenylether disulfonate with respect to 100 parts by mass of said graft copolymer (B), and a calcium salt compound as a coagulating agent, wherein the graft copolymer (B) consists of polymerized monomer units of the methylmethacrylate, the butadiene and one or more selected from the group consisting of an aromatic vinyl monomer, an alkyl (meth)acrylate monomer, an unsaturated nitrile monomer, halogenated vinyl monomer and a vinyl ether monomer.
