摘要
采用DSC方法研究了双峰聚乙烯(BPE)和茂金属聚乙烯(mPE)的非等温结晶过程,分别采用Ozawa方程和莫志深方法对所得的数据进行了处理。结果表明:茂金属聚乙烯结晶速率高于双峰聚乙烯。在实验范围内,两种聚乙烯的非等温结晶动力学均符合莫志深方程。
The non-isothermal crystallization behavior of bimodal polyethylene（BPE） and metallocene polyethylene （mPE） were studied by DSC. The DSC data was analyzed through the methods of Ozawa and Mo Zhishen. The result showed that the crystallization rate of roPE was faster than that of BPE. The crystallization kinetics of BPE and roPE in non isothermally was fitted for the Mo Zhishen equations in the range of experiments.
