摘　　要：大区域取向对非晶态聚对苯二甲酸乙二酯结晶的影响林辛，吴永升，高金贵，范庆荣（中国科学院化学研究所北京１０００８０）关键词聚对苯二甲酸乙二酯，溶剂诱导结晶，大区域取向Ｓｌｏｎｉｍｓｋｙ等’‘’“最早注意到区分小区域取向和大区域取向的概念，钱人元等”’对...ffects of the chain orientation in the global sense on the solvent induced crystallization (SINC),diffusion velocity of toluol into poly(ethylene terephtlialate)(PET)and crystallization morphology were:studied by using density measurement and SEM.It has been shown that the SINC and diffusion velocity of toluol into PET increase with increasing degree of chain orientation in global sense,and the chain orientatioll can be essentially remained during SINC.
