【摘要】 α-二亚胺镍配合物催化乙烯均聚可得到高度支化的聚乙烯,通过改变α-二亚胺镍配合物自身结构以及外界聚合条件(聚合温度、乙烯压力、助催化剂等),可以精细调控聚乙烯的支化度,从而得到不同性质的聚乙烯材料。更多还原

【Abstract】 Theα-diimine nickel complex catalyzes the homopolymerization of ethylene to give highly branched polyethylene.By changing the structure of theα-diimine nickel complex and the external polymerization conditions(polymerization temperature,ethylene pressure,cocatalyst,etc.),the degree of branching of the polyethylene can be finely controlled to obtain polyethylene with different properties.更多还原
