    • PURPOSE: A polyamide composition, its preparation method, a molded product prepared from the composition and a semi-aromatic polyamide used to the composition are provided, which composition shows an excellent heat aging characteristic as well as good resistance against heat, impact, hot water and chemicals, a low water absorption property and a good dimensional stability and is suitable as a component used at a high temperature such as an engine room parts of an automobile. CONSTITUTION: The semi-aromatic polyamide has a dicarboxylic acid unit mainly composed of an aromatic dicarboxylic acid unit and a diamine unit mainly composed of an aliphatic diamine unit of C4-C14, and its terminal amine group is 15 μeq/g or less. The polyamide composition comprises 100 parts by weight of the semi-aromatic polyamide; and 0.01-5 parts by weight of a copper compound. Preferably the composition comprises further 1-20 parts by weight of an alkali metal halide based on 1 part by weight the copper compound; and/or 1-60 parts by weight of a filler based on the total weight of the composition. Preferably the copper compound is a copper (I) compound; and more preferably the copper compound is CuI and the alkali metal halide is KI.
