Abstract:
A fluorine-containing polyamide with a logarithmic viscosity of 0.01 to 3.00 dL/g determined at 35.degree. C. by dissolving 0.5 gram of the polyamide in hexamethyl phosphoric triamide comprising a repetitive unit represented by general formula (4) formed by condensation polymerization at least one of diamines represented by general formula (2) with at least one of dicarboxylic derivatives represented by general formula (3); ##STR23## where a is the same or is different from each other, and is an integer of 0 to 4 whose total number is at least one; R.sub.3 is the same or is different from each other, and is a monovalent group represented by C.sub.k F.sub.2k+1 ; and k is an integer of 0 to 6; ##STR24## wherein x.sub.1 is a halogen atom, hydroxy, methoxy or ethoxy, and Ar.sub.3 is at least one group selected from the group consisting of a fused polycyclic aromatic group and a bivalent group represented by formula (o); ##STR25## wherein M is a direct bond or a bivalent group selected from the group consisting of --O--, --S--, SO.sub.2 --, --CO--, CH.sub.2 --, --C(CH.sub.3).sub.2 -- and --C(CF.sub.3).sub.2 -- and when appearing two or more times in the structural formula, M is the same or is different from each other; R.sub.4 is a monovalent group selected from the group consisting of an alkyl, a perfluoroalkyl and an alkoxy having 1 to 6 carbons, a halogen atom and phenyl, and when appearing two or more times in the structural formula, R.sub.4 is the same or is different from each other; b is an integer of 0 to 2; and c is an integer of 0 to 4 and when appearing two or more times in the structural formula, c is the same or is different from each other; ##STR26## wherein R.sub.3, a and Ar.sub.3 are as defined above.
