Nickel Catalysts for Non‐Alternating CO‐Ethylene Copolymerization

Transition metal-catalyzed copolymerization of CO and ethylene has a strong inherent propensity to produce the strictly alternating copolymer. In this work, nickel catalysts capable both homopolymerization are developed explore possibility non-alternating under assumption that comonomer incorporation in polymer chain can be adjusted by concentrations comonomers. Both polyketones with slightly more than 50 % “polyethylenes” small amount obtained but only carefully controlled conditions low yields.
