Summary: | PROBLEM TO BE SOLVED: To provide a copolyamide being excellent in heat stability at a high temperature, heat discoloration-resistance and moldability. SOLUTION: The copolyamide comprises (a) a unit comprising (a-1) 1,4-cyclohexanedicarboxylic acid and (a-2) a 6-8C aliphatic diamine, (b) a unit comprising (b-1) an aliphatic dicarboxylic acid and/or an alicyclic dicarboxylic acid other than 1,4-cyclohexanedicarboxylic acid and (b-2) a 6-8C aliphatic diamine, and (c) a unit comprising a lactam and/or an aminocarboxylic acid. In the copolyamide, the (a) is 13.0-40.0 mol%, the (b) is 50.0-86.9 mol%, and the (c) is 0.1-10.0 mol%. COPYRIGHT: (C)2010,JPO&INPIT |
