Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a rubber-reinforced styrene resin composition for high- transfer blow molding, having excellent blow-moldability and capable of producing a molded article having excellent appearance. SOLUTION: This composition is composed of (A) 100 pts.wt. of a rubber- reinforced styrene resin and at least one kind of polymer selected from (B) 0.1-20 pts.wt. of a styrene resin having a weight-average molecular weight of >=500,000, (C) 0.01-10 pts.wt. of a polytetrafluoroethylene having a weight-average molecular weight of >=500,000 and (D) 0.1-20 pts.wt. of a polymer composed mainly of a (meth)acrylic acid ester and having a weight-average molecular weight of >=500,000. The resin composition is blow-molded by keeping the temperature of the mold surface above the Vicat softening temperature of the composition.
