PURPOSE:To obtain the title composition improved in compatibility and excellent in mechanical strengths, flexibility, heat resistance, etc., by adding a specified vinyl copolymer to a mixture of a specified polyamide resin with a thermoplastic polyester resin. CONSTITUTION:0.1-10 pts.wt. vinyl copolymer comprising 40-99wt.% vinyl monomer of formula I (wherein R1 is H or lower alkyl; R2 is phenyl, cyano or an alkyl ester group with 1-10C alkyl) and 60-1wt.% vinylic glycidyl ester monomer of formula II (wherein R3 is H or lower alkyl) [e.g. glycidyl methacrylate/styrene (20/80wt.%) copolymer] is added to 100 pts.wt. mixture comprising 10-90wt.% polyamide resin (e.g. nylon 12) having a molar ratio of the terminal amino groups to the terminal carboxyl groups of 1.5 or above and 90-10wt.% thermoplastic polyester resin (e.g. polybutylene terephthalate resin) to obtain the title composition. |
