Abstract
PURPOSE: To prepare a melt-moldable copolyamide having excellent transparency and flexibility, by polymerizing ε-caprolactam together with the nylon salt of an aromatic dicarboxylic acid and an alicyclic diamine.
CONSTITUTION: A mixture comprising (A) ε-caprolactam, (B) the nylon salt of an aromatic dicarboxylic acid (e.g. isophthalic acid, etc.) and bis-(4-aminocyclohexyl)- methane, and (C) the nylon salt of an aliphatic dicarboxylic acid (e.g. adipic acid, etc.) and hexamethylenediamine, is polymerized to give a copolyamide wherein (a) the amount of the recurrent unit I is ≥ 70 wt.%, and (b) the molar ratio of the unit II to the unit III (n is integer of 4W10) is ≤ 1. The relative viscosity of the copolymer is preferably ≥ 1.3.
