| 摘要 |
Provided is a polyamide composition comprising 100 parts by weight of (A) a semiaromatic polyamide having dicarboxylic acid units mainly composed of aromatic dicarboxylic acid units and diamine units mainly composed of aliphatic diamine units having 4 to 14 carbon atoms and containing not more than 15 µ eq/g of terminal amino groups; and 0.01 to 5 parts by weight of (B) a copper compound. The polyamide compositions of the present invention have excellent heat aging characteristics, as well as excellent mechanical characteristics, low-water-absorption property and dimensional stability. The polyamide compositions of the present invention can be used as molding materials for industrial materials or household goods and are, especially, suited for a various article, which is used at a high temperature, such as engine room parts of an automobile.
