A literature review addresses the synthesis and characteristics of copoly(ether-ester)s containing a liquid crystal polyester segment. Multiblock copoly(ether ester)s have a poly[p,p'-bis(alkylene benzoate)] or a polyester hard segment based on terephthalic acid and hydroquinone, copoly(ether ester)s of terephthalic acid and hydroquinone, copoly(ether ester)s of terephthalic acid and p-hydroxybenzoic acid, and photoreactive copoly9ether ester)s. Blends of thermotropic polyesters with block elastomers have specific mechanical properties imparted by the liquid crystal phase. Oriented filaments in the thermoplastic matrix result in the formation of self reinforced (in situ) composites that represent a new class of engineering materials. 99 refs.
