Abstract
Copolymerization of Ni(H) or Co(II) acenaphthene diimine complexes containing olefinic substituents on aryl groups in the presence of a free radical initiator results in polymerized late transition metal catalysts which can be used for olefin polymerization or oligomerization. These catalysts have high catalyst activity for olefin polymerization or oligomerization.
