The crystallization and melting behavior of mellocene - catalized branched and linear polyethylenes of low molecular weight was studied . it was found that the crystalline lattice of branched polyethylene is larger than that of linear polyethylene because of the existence of branched chains . the melting behavior of branched polyethylene is similar to that of linear polyethylene since the branched chains can not enter the lattice . however , the crystalline behavior of low molecular weight branched polyethylene is the same as that of high molecular weight linear polyethylene , but different with that of low molecular weigh linear polyethylene . kinetics theory analysis evidenced that the transition temperature of growth regime of the branched polyethylene is about 20 lower than that of linear polyethylene with the same molecular weight . it may be attributed to the existence of short branched chains 研究了金属茂催化的低分子量支化聚乙烯和线性聚乙烯的结晶及熔融行为,发现支化聚乙烯的结构与线性聚乙烯相同为正交结构,但晶格略有膨胀.支链的存在对熔融行为影响不大,两种聚乙烯的熔点均随结晶温度的升高而非线性增加,表现出低分子量样品的共同特征.但支链的存在对结晶行为却有很大的影响,主要是由于支链的存在降低了晶体的结晶速率从而影响结晶过程,使得低分子量的支化聚乙烯的结晶行为与高分子量线性聚乙烯的结晶行为相似而与低分子量的线性聚乙烯不同.动力学分析表明,低分子量的支化聚乙烯的结晶生长方式的转变温度比同等分子量的线性聚乙烯降低了约20
