Abstract
The effect of thermally annealing five non-crystalline liquid-crystall ine copolyesters, each derived from five or more different ester-formi ng monomers, has been examined. Four of the compositions developed low crystallinity, which was sufficient to suppress flow at temperatures below the melting temperature of crystallites. The fifth developed no crystallinity and flowed at a temperature below 190-degrees-C.
