Abstract
Abstract An olefin dimerization catalyst system formed from (1) an organoaluminum compound and (2) a normally solid nickel complex which is the coordination product of a nickel compound and a substantially hydrocarbon-insoluble complexing solid polymeric component. In one embodiment, an effective olefin dimerization catalyst is formed from (1) ethyaluminum dichloride and (2) a nickel coordination product of nickel dichloride and poly(2vinylpyridine) cross-linked with divinylbenzene.
