PURPOSE:To obtain the titled composition, having excellent fluidity and tensile elongation in welded parts and good mechanical properties and impact strength, by blending a thermoplastic polyester polymer with a specific polyether polyamide elastomer. CONSTITUTION:A composition obtained by blending (A) a thermoplastic polyester polymer with (B) a polyether polyamide elastomer prepared by polycondensing a diamine containing polyether blocks having at least 3 ether oxygen atoms. with intervals mutually separated by a linear chain of at least 3 carbon atoms. or branched chain having at least 2 carbon atoms. with an almost equivalent amount of a dicarboxylic acid and laurolactam in an amount to provide 8-60wt.% weight ratio of above-mentioned polyether blocks based on the total polyether polyamide. |
