POLYAMIDE RESIN, METHOD FOR PREPARING SAME, AND MOLDED PRODUCT INCLUDING SAME

摘要

The present invention relates to a polyamide resin that is obtained by copolymerizing: (A) a dicarboxylic acid component including (a1) an aromatic dicarboxylic acid component; and (B) a diamine component including (b1) about 60 to about 70 mol% of an aromatic diamine component and (b2) about 30 to about 40 mol% of piperazine. Further, the present invention is characterized in having a repeating structure of a dicarboxylic acid moiety derived from the dicarboxylic acid component (A) and a diamine moiety derived from the diamine component (B). The polyamide resin has excellent processability, heat-resistance, and dimensional stability.
