Melt processable optically anisotropic polymer processing

摘要

A process comprising synthesizing a liquid crystal polyester consisting essentially of recurring moieties of formulas: <IMAGE> I. and <IMAGE> II. and moiety III or IV wherein III is <IMAGE> and IV is <IMAGE> wherein the mole ratio of moiety II to moiety III, when present, is 1:4 to 2:1 and wherein the mole ratio of moiety II to moiety IV, when present, is 2:8 to 1:9 and devolatilizing said liquid crystal polyester prior to shaping such polyester into an article and then shaping said devolatilized polyester into said article.
