CA 2642827

Disclosed are a fiber which is excellent in mechanical strength such as tensile strength and elastic modulus, and a polyamide as a raw material for such a fiber. Specifically disclosed is a polyamide (X) mainly containing repeating units represented by the formula (A) and the formula (B) shown below, and having an inherent viscosity of 0.05-20 dL/g as measured in a concentrated sulfuric acid solution at a concentration of 0.5 g/100 mL at 30~C. The polyamide (X) contains a substituent represented by the formula (C) below in at least a part of the ends. Also specifically disclosed is a fiber made of the polyamide (X). (A) (B) (C) (In the formula, Ar3 represents a trivalent aromatic hydrocarbon group having 6-20 carbon atoms, and Ar4 represents a monovalent aromatic hydrocarbon group having 6-20 carbon atoms.)

L'invention concerne une fibre laquelle est excellente en termes de résistance mécanique telle que la résistance à la rupture par traction et le module élastique et un polyamide servant de matière première pour une telle fibre. L'invention concerne précisément un polyamide (X) contenant principalement des unités récurrentes représentées par la formule (A) et la formule (B) indiquées ci-dessous et ayant une viscosité intrinsèque de 0,05-20 dl/g tel que mesurée dans une solution d'acide sulfurique concentrée à une concentration de 0,5 g/100 ml à 30°C. Le polyamide (X) contient un substituant représenté par la formule (C) ci-dessous sur au moins une partie des extrémités. L'invention concerne également précisément une fibre constituée du polyamide (X). (A) (B) (C) (Dans la formule, Ar3 représente un groupe hydrocarboné aromatique trivalent ayant 6-20 atomes de carbone et Ar4 représente un groupe hydrocarboné aromatique monovalent ayant 6-20 atomes de carbone).
