Claims
- 1. An aramid, carbon or glass fiber coated with a polymer consisting essentially of a copolyamide of the following units: ##STR4## where n is 4 or 5; X is from 0.01 to 0.50, preferably from 0.03 to 0.30, and Ar is a radical selected from 3,4'-oxydiphenylene, 4,4'-oxydiphenylene, 1,3-phenylene, 1-methyl-2,4-phenylene, and mixtures of such radicals with each other or with up to equimolar amounts of 1,4-phenylene radicals.
- 2. An aramid fiber according to claim 1 in which Ar is 3,4'-oxydiphenylene and the aliphatic unit is ##STR5##
