Abstract

PURPOSE: A specific aliphatic polyester-forming component and another specific aliphatic polyamide-forming components are mixed together and subjected to copolymerization to give the titled new polymer of high polymerization degree showing high mechanical strength, flexibility, impact strength and transparency.
CONSTITUTION: A polyester-forming component of formulaI(k is 8W10; l is 2W6) such as a condensate between straight-chained aliphatic diol and a dicarboxylic acid (5W50wt%) and a polyamide-forming component of formula II, III (m is 10, 11; n is 6W10; p is 8W10) such as 11W12C lactam or aminoacid and/or 6W10C diamine and 10W12C dicarboxylic acid(95W20wt%) are mixed, a polymerization catalyst is added thereto, and the polycondensation reaction is effected with heat under reduced pressure to produce the objective polyesteramide of uniformity, transparency and high polymerization degree.
