摘要：
Studies to establish the dependence of structural changes in injection moulded bars, extruded pellets and filaments from a liquid crystalline statistical copolyester on temperature profiles during annealing were performed using dynamic, rheological and thermoanalytical measurements. The shifts of the maxima in melt peak temperatures, the increases in degree of crystallization and molecular weight as well as the trans-esterification to block copolyesters were found to be depending on the temperature profiles during annealing.
