性に劣るため、その用途が限定されている。BACKGROUND OF THE INVENTION In general, aliphatic polyamides are excellent fibers and are widely used in clothing and the like. However, although aliphatic polyamide m-fibers have high elongation, their use is limited because they have lower strength, lower elastic modulus, and inferior heat resistance than aromatic polyamide m-fibers.

2. Heat resistance such as strength retention rate at high temperatures and mechanical properties such as strength ti ratio are extremely good. However, when made into fibers, not only do they have a low elongation of less than 5%, but the fibers themselves may become fibrillated and crack into multiple lines. This is thought to be due to the fact that the fibers are produced from aromatic polyamide by liquid crystal spinning.

ゾイル基が適している。That is, when the molar ratio of the chain member formula (C) of the copolyamide of the present invention exceeds 40, the solubility decreases. For example, when polymerizing terephthalic acid chloride, 9,9-bis(4-aminophenyl)fluorene, and hexamethylene diamine or propylene diamine in predetermined amounts in dimethylacetamide or N-methylpyrrolidone, some polymerization may occur during polymerization. The polyamide will precipitate, making it difficult to obtain a copolyamide with a high degree of polymerization. Further, the copolyamide terminals may be left untreated, but preferably the amino groups are acylated to make them less susceptible to oxidation. This acyl group is suitably an acetyl group or a benzoyl group.
