Abstract: PURPOSE: To obtain a copolyamide excellent in moldability, heat resistance, mechanical characteristics, chemical resistance, etc., by specifying the distribution of amide groups in the polymer chain and the crystallization characteristics. CONSTITUTION: A copolyamide is produced by forming a precondensate from a 4--14C aliph. diamine and terephthalic acid under the max. pressure of 5-23kg/ cm G at the max. temp. of 260-330 deg.C and melt extruding the precondensate with a twin-screw extruder having screw segments having an L/D of 2 or lower to form a polymer with a high degree of polymn. The copolyamide has the distribution of amide groups satisfying formulas l and II (wherein X is an amide group from a 4-14C diamine and terephthalic acid; Y is an amide group other than X; [XY] is the ratio of the amts. of X and Y present adjacently to the total amide groups; [XX] is the ratio of the amts. of X and X present adjacently to the total amide groups; calcd. indicates a value calculated; and obs. indicates a value observed) and has a half crystallization time satisfying formula III [wherein t1/2 is a half crystallization time (sec); Tm is the m.p.; and T is the temp. at which the half crystallization time is measured].
