ABSTRACT:
Fibers of arylene oxadiazole/arylene N-alkylhydrazide copolymer and of high tensile strength are prepared by a unique solution spinning process, whereby an arylene oxadiazole/arylene N-alkyloxadiazolium hydrosulfate copolymer in sulfuric acid or oleum is extruded into an aqueous coagulation medium in which concurrently a fiber is formed and the latter-mentioned copolymer undergoes a chemical transformation to provide the first-mentioned copolymer.
