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(jié)晶及熔融行為,發(fā)現(xiàn)支化聚乙烯的結(jié)構(gòu)與線性聚乙烯相同為正交結(jié)構(gòu),但晶格略有膨脹.支鏈的存在對(duì)熔融行為影響不大,兩種聚乙烯的熔點(diǎn)均隨結(jié)晶溫度的升高而非線性增加,表現(xiàn)出低分子量樣品的共同特征.但支鏈的存在對(duì)結(jié)晶行為卻有很大的影響,主要是由于支鏈的存在降低了晶體的結(jié)晶速率從而影響結(jié)晶過程,使得低分子量的支化聚乙烯的結(jié)晶行為與高分子量線性聚乙烯的結(jié)晶行為相似而與低分子量的線性聚乙烯不同.動(dòng)力學(xué)分析表明,低分子量的支化聚乙烯的結(jié)晶生長(zhǎng)方式的轉(zhuǎn)變溫度比同等分子量的線性聚乙烯降低了約20
