PROBLEM TO BE SOLVED: To provide a copolymerized polyamide which is excellent in strength, low water absorption and low volatile component at molding, and has low environmental load, as well as a copolymerized polyamide composition having excellent melt-flowability at molding and excellent surface appearance.SOLUTION: The copolymerized polyamide contains (a) a unit comprising alicyclic dicarboxylic acids, (b) a unit comprising a diamine having 8 carbon atoms or more, (c) a unit comprising a diamine having less carbon atoms than that of the diamine of (b) and (d) a unit comprising a terminal sealant. The copolymerized polyamide composition contains the copolymerized polyamide and one or more components selected from a group consisting of an inorganic filler, a nucleating agent, a lubricant, a stabilizer and a polymer other than the copolymerized polyamide. |
