PREPARATION OF POLYBENZOXAZOLES FROM HALOGENATED POLYAMIDE ANIONS

This invention relates to a process for making polymers containing benzoxazole groups by heating, and thereby dehalogenating, novel anions of orthohalogenated aromatic amide groups of a polyamide. The products are useful as fibers and films.
