    Abstract: Novel liquid crystalline extended chain polymer compositions comprising a high concentration of one or more extended chain homopolymer(s), copolymer(s), or block polymer(s) and certain strong acids are prepared by admixing a high concentration of one or more selected homo- or hetero-bifunctional monomer(s) with or without oxidation protecting atoms or groups and one or more of a substantially non-oxidizing strong acid(s) having a high or low P.sub.2 O.sub.5 content. Such compositions are capable of exhibiting excellent cohesive strength, and are especially suited to the production of high molecular weight ordered polymer fibers by dry-jet wet spinning. These liquid crystalline compositions are capable of being drawn through long air gap distances and spun at exceptionally high spin draw ratios. Fibers, films and other articles formed from these liquid crystalline compositions exhibit exceptionally high physical and heat resistant properties.

    Abstract: Hydroxyalkyl- and aminoalkyl-functionalized polyphenylene ethers are prepared by the reaction of polyphenylene ethers with bis-hydroxyalkyl maleates or fumarates, or with the corresponding acids or anhydrides, terephthaloyl chloride or the like followed by esterification or imidization with diols, diamines or amino alcohols. They are useful in the preparation of polyphenylene ether copolymers, which in turn are useful for the compatibilization of blends of polyphenylene ethers with linear polyesters.
