STUDIES OF SOLVENT INDUCED CRYSTALLIZATION OF POLY (ETHYLENE TEREPHTHALATE) II. FORMATION OF SURFACE AND FRACTURE MORPHOLOGY
聚对苯二甲酸乙二酯溶剂诱导结晶研究——Ⅱ.表层与断面结构形态形成的探讨

The morphology of quenched poly(ethylene terephthalate) "PET" films crystallized by several kinds of organic solvents or it's saturated vapors axe studied by tre SEM, SALS and PLM. It has been shown that the spherulite ball like structure is formed only in the surface-layer, and the structure of fracture can be divided into three layers according to difference of morphology. Depth of diffusion (A) dependson the time of solvent treatment (t). The plot of h vs t1/2 is linear.
