PURPOSE:To provide a thermoplastic polymer compsn. having excellent rigidity, flow characteristics and heat distortion resistance and suitable for use as a material for a molding of an automobile, by blending an amine compd. and a polymer such as polyamide with an ethylene/unsaturated carboxylic acid copolymer. CONSTITUTION:100pts.wt. ethylene/unsaturated carboxylic acid copolymer (A) (e.g. ethylene/acrylic acid copolymer) or crosslinked product (A) of zinc, cobalt, nickel, copper, lead or magnesium ion thereof, 0.5-30pts.wt. amine compd. (B) contg. at least two primary or secondary amino groups (e.g. hexamethylenediamine) and 1-200pts.wt. polymer or oligomer (C) selected from among polyamides (oligomers), polyalkylene terephthalates and monovalent metal salts of ethylene/unsaturated carboxylic acid copolymers are mixed together to obtain the desired thermoplastic polymer compsn. having excellent rigidity. |
