摘 要：The effects of thermal treatment on microstructure of the Polyesters were studied. Annealing below Tc-n, physical diffusion PrOCesses dominate to yield an increasing crystallinity along with increased molecular weight transesterification reactions are limited to the end groups and the microstructure had not changed Annealing near Tc-n, chemical processes dominate and simultaneously make the microdomains ordered more perfectly. Analysis by 13C NMR Proved that interchain transesterification had occurred.
