摘要：
This invention seeks to provide a fiber formed of an aromatic polyazole that has a high molecular weight and is excellent in mechanical properties such as elastic modulus, strength, etc., and a process for the production thereof.This invention provides a fiber formed of a polyazole containing a recurring unit of the following formula (1), wherein Ar1 is a divalent aromatic group having 4 to 20 carbon atoms, Ar2 is a tetravalent aromatic group having 4 to 20 carbon atoms and each X is O, S or NH, and having a phosphorus atom content of 30 ppm or less, and a process for the production thereof.
