PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having an excellent extrusion moldability. SOLUTION: A resin composition comprises 10 to 50 pts.wt. rubber-reinforced styrene resin (A) and 50 to 90 pts.wt. vinyl cyanide copolymer (B) obtained by copolymerizing a mixture comprising 85 to 45 wt.% aromatic vinyl monomer (1), 15 to 55 wt.% vinyl cyanide monomer (2) and 0 to 40 wt.% other vinyl monomer (3) copolymerizable with these. Against 100 pts.wt. resin composition, a vinyl cyanide copolymer (C) having a weight average molecular weight of 5,000,000 or larger, obtained by copolymerizing 85 to 45 wt.% aromatic vinyl monomer (1) and 15 to 55 wt.% vinyl cyanide monomer (2), and 0.05 to 5 pts.wt.α-olefin oligomer and/or ethylene/α-olefin cooligomer (D), are mixed. |
