  4. 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

    研究了金屬茂催化的低分子量支化聚乙烯和線性聚乙烯的結晶及熔融行為，發現支化聚乙烯的結構與線性聚乙烯相同為正交結構，但晶格略有膨脹.支鏈的存在對熔融行為影響不大，兩種聚乙烯的熔點均隨結晶溫度的升高而非線性增加，表現出低分子量樣品的共同特徵.但支鏈的存在對結晶行為卻有很大的影響，主要是由於支鏈的存在降低了晶體的結晶速率從而影響結晶過程，使得低分子量的支化聚乙烯的結晶行為與高分子量線性聚乙烯的結晶行為相似而與低分子量的線性聚乙烯不同.動力學分析表明，低分子量的支化聚乙烯的結晶生長方式的轉變溫度比同等分子量的線性聚乙烯降低了約20
