介绍了两种线性低密度聚乙烯 (LLDPE)（一种高度支化，另一种低支化）的完整 C-13 NMR 表征。这些LLDPE是用一种新的催化剂：[eta(3)-甲代烯丙基-镍-dad]PF6络合物，通过乙烯均聚反应合成的，使用不同的实验条件，对甲基、乙基、丙基、丁基、戊基和长支链进行了指定和定量。
A complete C-13 NMR characterization of two linear low-density polyethylenes (LLDPE), one highly branched and the other lowly branched, is presented. These LLDPE were synthesized with a new catalyst: the [eta(3)-methallyl-nickel-dad]PF6 complex by homopolymerization of ethylene, using different experimental conditions, Methyl, ethyl, propyl, butyl, amyl, and long branches were assigned and quantified.
