A complete 13 C 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 [η 3 -methallyl-nickel-dad]PF 6 complex by homopolymerization of ethylene, using different experimental conditions. Methyl, ethyl, propyl, butyl, amyl, and long branches were assigned and quantified.
