PURPOSE:To prepare the title compsn. excellent in impact resistance, moldability, etc., by compounding a mixture of a specific ABS resin with a polyamide resin with specified amts. of a hydrogenated bock copolymer modified with an alpha,beta- unsatd. carboxylic acid and an acrylic acid-modified resin. CONSTITUTION:20-80wt.% modified ABS resin obtd. by modifying 100 pts.wt. ABS resin with 0.1-5 pts.wt. alpha,beta-unsatd. carboxylic anhydride is mixed with 80-20wt.% polyamide resin contg. 0.01-0.1mmol/g terminal amino group and having a relative viscosity (as a soln. with 1g/dl conc. in 96% sulfuric acid) at 25 deg.C of 2-7. 100 pts.wt. resulting resin compsn. is compounded with 0.2-20 pts.wt. hydrogenated block copolymer comprising a vinyl arom. polymer block and an olefin polymer block and modified with an unsatd. carboxylic acid and 0.1-20 pts.wt. acrylic resin obtd. by copolymerizing a vinyl arom. compd., vinyl cyanide, and a (meth)acrylic ester, giving the title compsn. |
