Abstract
Abstract New nickel composition having substantial solubility in hydrocarbons and prepared by reacting at least one inorganic divalent compound, at least one halogenoacetic acid and at least one ester of the formula R 1 COO R 2 wherein R 1 is hydrogen or hydrocarbyl and R 2 is hydrocarbyl. The resultant composition can be used in admixture with a hydrocarbylaluminum halide as catalyst for olefin dimerization.
