Polyamide ester resin, method of preparing the same, and molded article including the same

Abstract

A polyamide ester resin is a polymer of: a dicarboxylic acid; a diamine; and a linear aliphatic diol, wherein, based on a total amount of the diamine and the linear aliphatic diol, the diamine is present in an amount of about 75 mol % to about 99 mol % and the linear aliphatic diol is present in an amount of about 1 mol % to about 25 mol %, and wherein the polyamide ester resin has a melting point (Tm) from about 280° C. to about 320° C. and a crystallization temperature (Tc) from about 260° C. to about 290° C. The polyamide ester resin can exhibit excellent heat resistance, discoloration resistance, and moldability.
