Novel liquid crystalline extended chain polymer compositions comprising a high concentration of one or more extended chain homopolymers, copolymers or block polymers and certain strong acids are prepared by admixing a high concentration of one or more selected monomers with or without oxidation protecting moieties and one or more of a substantially non-oxidizing strong acid(s) containing P2O5. Such compositions, which are prepared by polymerization in a reaction vessel maximizing surface-to-volume ratio , are capable of exhibiting high cohesive strength, and are especially suited to the production of high molecular weight ordered polymer fibers. Fibers, films and other articles formed from these liquid crystalline compositions exhibit exceptionally high physical and heat resistant properties.
