COPOLYMERIZED POLYAMIDE RESIN, METHOD FOR PREPARING THE SAME AND ARTICLE COMPRISING THE SAME

摘要

A copolymerized polyamide resin of the present invention is a polymer comprising a dicarboxylate component, and a mixture of monomer including a diamine component including 4-19 mole% of alicyclic diamine as displayed in chemical formula 1. A melting point (Tm) of the polymer ranges from 280 to 330°C, and a crystallization point (Tc) ranges from 250 to 300°C. The copolymerized polyamide resin has crystallizability, heat resistance, machinability, anti-discoloration, and excellent physical balance between the above properties. In chemical formula 1, R1 and R2 respectively and independently are an alkyl group with 1 to 5 carbons, or an aryl group of 6 to 10 carbons. m and n respectively and independently are an integer ranging from 0 to 4.
