摘　　要：用差示扫描量热法(DSC)研究了聚乙二醇(PEG)的非等温结晶动力学。用Ozawa法、Jeziorny法和莫志深法处理了PEG的非等温结晶数据。结果表明,PEG的非等温结晶过程可用Ozawa动力学方程描述,与Avrami动力学方程不符,采用Ozawa法和莫志深法处理数据可得到较好的线性关系,PEG的结晶速率参数为0.098。The non-isothermal crystallization kinetics of polyethylene glycol （PEG） was studied with differential scanning calorimetry. The non-isothermal crystallization data of PEG was analyzed by the methods of Ozawa, Jeziorny, and MO Zhi-shen. Results show that the non-isothermal crystallization process of PEG may be described with Ozawa kinetic equation, but does not agree with Avrami equation processed in the Jeziorny method. The linearity of treating non-isothermal crystallization kinetic curves with Ozawa method and MO Zhi-shen method is better. Parameter of crystallization velocity for PEG is 0.098.
