摘要
研究了几个典型的成核促进剂对聚对苯二甲酸乙二酯(PET)的结晶和形态的影响。成核促进剂促进了PET的分子运动,因而加速了低温结晶区的结晶速度;它也促进反常球晶的形成,对此提出了解释。
The influence of nucleating promoter on the crystallization and morphology ofpoly(ethylene terephthalate) (PET) has been studied. The nucleating promoter pro-mote molecular motion of PET and therefore increase the rate of crystallizationAlso nucleating promoter enhance the formation of abnormal spherulite and anexplanation has been given.
