Living polymerization of ethylene and α-olefins using a nickel α-keto-β-diimine initiator

摘要

A nickel α-keto-β-diimine initiator can be activated using treated methylaluminoxane (MAO) to generate active sites capable of the polymerization of ethylene, propene and 1-hexene under living conditions.rnRecent literature shows current interest in the transition metal mediated living polymerization of olefins. These reactions allow for the synthesis of polyolefins with higher order architectures and improved physical properties.
