Abstract: Polycarbonate resins are chain-terminated with a group selected from those of the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently selected from the group consisting of hydrogen, halogen, hydrocarbyl of from 1 to 12 carbon atoms, inclusive; and halogen-substituted hydrocarbyl of 1 to 12 carbon atoms, inclusive; R.sub.1 is attached to a ring carbon atom at one of the 4, 5 or 6 positions; and R.sub.2 and R.sub.3 when taken together represent the divalent moiety of formula:--CH.dbd.CH.sub.2 --CH.sub.2 .dbd.CH--which effectively creates an additional fused aromatic ring structure. The resins exhibit a low plate-out when processed thermally.

Abstract: Novel compositions comprising a high concentration of one or more extended chain homopolymer, copolymer, or block polymer and certain polyphosphoric acids are prepared. Such compositions are optically anisotropic (liquid crystalline), 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.
