摘　　要：利用差示扫描量热方法,考察在不同溶剂下的乙烯齐聚产物数均分子量及其相对分子质量分布,同时根据热失重数据比较不同溶剂作用下乙烯齐聚产物的热稳定性,得到溶剂结构对乙烯齐聚产物相对分子质量分布的影响规律。The number average molecular weight and distribution of products by oligomerzation of ethylene in different solvents was analyzed by DCS, meanwhile the heat stability of these products was studied by TGA, and the influencing rule of solvent for molecular weight distribution was obtained.

关 键 词：差示扫描量热 热失重 乙烯齐聚 溶剂 数均分子量
