摘　　要：以聚 4-甲基戊烯 - 1(PMP)为膜材质 ,分别以环己烷、三氯乙烯以及环己烷 /三氯乙烯为溶剂 ,以浇铸法制备了PMP的均质致密膜。研究了不同溶剂体系的相对溶解能力和挥发速度对PMP膜结晶度和形态结构的影响 。Using Poly(4 methyl pentene 1)(PMP) as a membrane material and cyclohexane, trichloroethylene, mixture of cyclohexane and trichloroethylene as solvents, these solutions were cast to form homogeneous dense membranes, respectively. The crystalline properties of the membranes were investigated by DSC. The results showed that the crystalline form and crystallinity of PMP membrane are closely related to the solubility and evaporation rate of the solvents. And the effects of solvents on the pervaporation behavior of PMP membranes were also studied.
