| titleOfInvention | Copolymerized polyamide and process for its production |
| abstract | A copolymerized polyamide comprises amide bonds formed from an aliphatic diamine with 4 to 14 carbon atoms and terephthalic acid and having existence ratios defining the distribution of respective adjacent amide bonds and satisfying the following formulae (A) and (B): 0.9 ≦ [XY] obs./[XY] calcd. < 1.1 0.9 ≦ [XX] obs./[XX] calcd. < 1.1 n wherein X stands for an amide bond formed from an aliphatic diamine with 4 to 14 carbon atoms and terephthalic acid; Y stands for any other amide bond than X; or, for copolymers where all amide bonds are bonds X, bonds formed from one said diamine count as X and the remainder as Y; [XY] refers to the number of occurrences in which X and Y are adjacent to each other among all the amide bonds in the polymer structure; [XX] refers to the number of occurrences in which X and X are adjacent to each other among all the amide bonds in the polymer structure; [XY] calcd. and [XX] calcd. are respectively the values of [XY] and [XX] calculated on the assumption that X and Y amide bonds are distributed statistically at random, and [XY] obs. and [XX] obs. are respectively the values of [XY] and [XX] measured from the copolymerized polyamide. n The copolymerized polyamide has a half-crystallization time which satisfies the following formula (C): 4.4 - 0.1 (Tm - T) ≦ log tl/2 < 5.5 - 0.1 (Tm - T) n wherein t1/2 is the half-crystallization time (seconds); Tm is the melting point (°C) of the polymerized polyamide; and T is the temperature (°C) at which the half-crystallization time is measured. |
