A process comprising synthesizing a liquid crystal polyester consisting essentially of recurring moieties of formulas: ##STR1## and moiety III or IV wherein III is ##STR2## 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.

Melt processable optically anisotropic polymer processing

Styrene and hydroquinone are reacted to produce (1-phenylethyl) hydroquinone, i.e., ##STR1##

Synthesis of styrenated hydroquinone

Melt spinnable liquid crystal aromatic polyesters which are optically anisotropic in the melt phase are provided. The polyester is a poly [(1-phenylethylphenylene)/chlorophenylene terephthalate].

Melt processable optically anisotropic polyesters

Melt spinnable liquid crystal aromatic polyesters which are optically anisotropic in the melt phase are provided. The polyester is a poly [(1-phenylethyl)-phenylene/phenylene terephthalate].

Melt spinnable, liquid crystal aromatic polyesters which are optically anisotropic in the melt phase are provided.
