  • Polyamide ester resin, method for preparing the same, and molded article including the same
    Patent number: 9580552
    Abstract: 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 the following Formula 1, wherein the polyamide ester resin has a melting temperature (Tm) of about 280° C. or more. The polyamide ester resin can exhibit excellent properties in terms of moisture absorption resistance, heat resistance, discoloration resistance, fluidity and the like by using a cyclic ester. wherein R1 is a C3 to C12 linear, branched or cyclic alkylene group.

  • Polyamide Resin, Method for Preparing the Same, and Molded Article Including the Same
    Publication number: 20160096924
    Abstract: A polyamide resin is a polymer of an adipic acid-containing dicarboxylic acid component and an m-xylenediamine-containing diamine component, wherein the polymer includes about 100 ppm or less of phosphorus and about 100 ppm or less of sodium (Na), and has a gel content of about 0.5% or less as measured on a specimen prepared by melting about 10 g of the polymer at about 260° C., maintaining the molten polymer for about 30 minutes, and then cooling the molten polymer to room temperature. The polyamide resin can exhibit excellent heat resistance and can reduce or prevent gel generation upon polymerization or molding.
