    摘要: Heterocyclic aromatic polymers are rapidly formed by contacting one or more appropriate multifunctional aromatic monomers, such as a diaminobenzenediol, a terephthaloyl halide and/or an aminohydroxybenzoic acid, with a sulfonic acid, as the solvent, and a dehydrating agent.

    摘要: The invention is a process for making novel branched polybenzazole polymers and the polymers formed thereby. Novel compounds are also disclosed that are useful as branching agents in making the branched polybenzazole polymers. The branched polymers synthesized by the process can be formed into strong, light articles such as fibers and films.
