ABSTRACT:
A thermoplastic resin composition composed of a mixture comprising a graft polymer obtained by subjecting a monomer mixture of an aromatic vinyl monomer and a vinyl cyanide monomer to emulsion polymerization in the presence of a diene rubber latex, and a hard polymer obtained by copolymerizing a monomer mixture of an aromatic vinyl monomer and a vinyl cyanide monomer, in which the number average particle size Dn of diene rubber particles contained in the composition is at most 0.1 .mu.m, the ratio (Dw/Dn) of the weight average particle size Dw to the number average particle size Dn of the diene rubber particles is at least 5.0, the graft rate of said graft polymer is at least 60%, and the content of an emulsifier and a reaction product of an emulsifier is not higher than 2% by weight.
