Abstract

PURPOSE: Titled copolyamide, excellent in dyeability, heat resistance, etc., and suitable as a material for forming a fiber or film, which comprises dicarboxylic acid repeating units and at least two kinds of diamine repeating units, in a specified ratio.
CONSTITUTION: Titled copolyamide is composed of (a) a dicarboxylic acid unit, represented by at least one repeating unit of formula I or II, (b) at least one repeating unit of formula III, IV or V, and (c) a diamine repeating unit, represented by at least one repeating unit of formula VI or VII. Where at least one dicarboxylic acid repeating unit of formula I, or II, is equal at least one diamine repeating unit of formula IV or V, and to at least one repeating unit of formula VI and VII, in mol, and 2W25mol%, based on the total of the repeating units, of at least one repeating unit of formula VI or VII are contained.
