文摘

A nickel α-keto-β-diimine initiator (1), when activated with methylaluminoxane (MAO) generates active sites capable of polymerizing α-olefins to high molecular weight products. Herein, we report on the full characterization and detailed microstructural analysis of poly(1-hexene) (PH) homopolymers obtained by using the 1/MAO combination. ¹³C NMR spectroscopy was used to provide the first qualitative and quantitative determinations of all the sequences in the poly(1-hexene). Such information yields insight into the reactivity of this novel catalytic system.
