摘要：

The crystallization behaviour of poly(ethylene terephthalate) (PET) and its blends with a liquid crystal polymer (Rodrun 3000) was studied by differential scanning calorimetry (d.s.c.), under both non-isothermal and isothermal conditions. The theories of Ozawa and Avrami were applied to study the kinetics of non-isothermal and isothermal crystallization respectively. In both cases it was found that a very low percentage of a thermotropic Liquid crystal polymer (TLCP) determines an increase in the overall crystallization rate, while increasing the amount of TLCP results in a progressive decrease in the crystallization rate and the melting temperature. However, the crystallinity of PET in the blends was found to increase on increasing the TLCP content. (C) 1998 Elsevier Science Ltd. All rights reserved.
