To provide thermoplastic resin compositions ranging from a rigid to a flexible type which are excellent in impact resistance, chemical resistance, fluidity, glossiness, molding shrinkage, appearance and sliding properties and are sufficiently weldable both to a styrene-based resin and to a polyolefin resin.
The thermoplastic resin composition is obtained by blending (A) a styrene-based resin obtained by polymerizing an aromatic vinyl monomer, a (meth)acrylate monomer, a vinyl cyanide monomer and one or more monomers or a mixture thereof selected from the group consisting of other monomers copolymerizable with these monomers, (B) a polyolefin resin and (C) a graft copolymer obtained by polymerizing an aromatic vinyl monomer, a (meth)acrylate monomer, a vinyl cyanide monomer and one or more monomers or a mixture thereof selected from the group consisting of other monomers copolymerizable with these monomers in the presence of an ethylene-propylene-based rubbery copolymer containing a polyolefin resin.
