PET／PMMA共混体系的结晶行为

Crystallization Behavior of Blends of Polyethylene Terephthalate and Polymethyl Methacrylate

对聚对苯二甲酸乙二酯（ＰＥＴ）在繁甲基丙烯酸甲酯（ＰＭＭＡ）存在下的结晶行为进行了比较详细的讨论。

Blends of poly(ethylene terephthalate)(PET)and poly(methyl methacrylate)(PMMA)were prepared by molten mixing,and crystallization behavior of the blend was characterized by differ-ential scanning calorimetry(DSC) and depolarization method.The effects of PMMA on crystallizationbehavior of PET are discussed.PMMA is able to promote crystalization of PET。
