PURPOSE:To provide the titled compsn. having excellent impact resistance, durability and toughness, by blending a polyether ester amide with a linear arom. polyester. CONSTITUTION:At least one compd. (a) (e.g. 12-amino-dodecanoic acid) selected from among 6C or higher aminocarboxylic acids and lactams and salts of 6C or higher diamines with dicarboxylic acids, a poly(alkylene oxide) glycol (b) having a number-average MW of 300-6,000, such as poly(tetramethylene oxide) glycol, and a 4-20C dicarboxylic acid (c) such as dodecanedioic acid are solution-polymerized and the polymerization is then accelerated under high vacuum to obtain a polyether ester amide (A). 1-50wt% component A is blend ed with 99-50pts.wt. linear arom. polyester (e.g. polybutylene terephethalate) obtd. by condensing an arom. dicarboxylic acid with a diol as main components. |
