PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition used for blow molding and excellent in impact resistance by mixing a rubber-containing graft copolymer, a vinyl cyanide copolymer, a carboxylated copolymer, a compound represented by a specified formula, a rubber agglomerate and a vinylic copolymer. SOLUTION: A mixture of 5-50wt.% acrylonitrile, 10-90wt.% styrene and 0-80wt.% methyl methacrylate is copolymerized in the presence of 20-80 pts.wt. diene rubber to produce a rubber-containing graft copolymer. 10-50 pts.wt. of this copolymer is mixed with 10-80 pts.wt. vinyl cyanide copolymer consisting of 15-55wt.% acrylonitrile and 85-45wt.% styrene, 1-15 pts.wt. carboxylated copolymer consisting of 5-50wt.% acrylonitrile, 10-90wt.% styrene and 1-10wt.% acrylic acid, 0.01-10 pts.wt. compound represented by the formula (wherein R1 , R2 and R3 are each H, a 1-26C alkyl, etc.; and Y is N or CON), 0-30 pts.wt. rubber agglomerate, and 0-50 pts.wt. vinylic copolymer consisting of 5-30wt.% acrylonitrile, 75-45wt.% styrene and 0-60wt.% maleimide to give a thermoplastic resin composition for blow molding. |
