Random and block copolyesters which are liquid crystalline can be formed containing: (a) alkoxy-substituted para-phenylene terephthalate groups (i.e., derived from an analogously substituted hydroquinone reagent); and (b) alkylene-terephthalate groups (e.g., where the alkylene moiety contains 2 to 10 carbon atoms).

Liquid crystal copolymer containing alkoxy-substituted para-phenylene

Thermotropic liquid crystalline poly(ester-amide) compositions are disclosed which comprise a bis(4-carbonyl phenylene) terephthalate unit and a unit derived from an N-substituted hydrocarbylenediamine (e.g., one derived from an N,N-dialkylalkylene).

Thermotropic liquid crystalline poly(ester-amides)

A copolymer of (1) a triad aromatic ester mesogenic unit containing a flexible polyalkylene spacer in the main chain thereof and (2) a polyester is disclosed.

Copolymer of liquid crystal triad aromatic ester mesogenic unit with

Liquid crystalline polyesters of the aromatic triad type are formed by reaction of an alkylene bis(acetoxybenzoate) monomer and an aromatic dicarboxylic acid monomer with removal of acetic acid by-product therefrom.

Process to synthesize liquid crystalline polyesters

Novel liquid crystal polyesters can be formed by reaction of bis(hydroxyalkoxy)biphenyls (including the novel bis(2-hydroxybutoxy)biphenyl) with terephthaloyl chloride.
