POLYAMIDE ESTER RESIN, METHOD FOR PREPARING THE SAME, AND MOLDED ARTICLE INCLUDING THE SAME

摘要

A polyamide ester resin includes: a repeat unit derived from a dicarboxylic acid; a repeat unit derived from a diamine; and a repeat unit represented by Formula 1, wherein the polyamide ester resin has a melting temperature (Tm) of 280°C or more. The polyamide ester resin exhibits excellent properties in terms of moisture absorption resistance, heat resistance, discoloration resistance, fluidity and the like by applying a cyclic ester.
wherein R 1 is a C 3 to C 12 linear, branched or cyclic alkylene group.
