Abstract
A process for producing an olefin oligomer comprising polymerizing olefin having not less than 6 carbon atoms in the presence of a catalyst consisting essentially of (a) aluminum halide, (b) polyhydric alcohol derivative of which alcohol the hydrogen atoms of the entire hydroxyl groups are substituted with either one or both of alkyl and acyl groups and (c) a nickel compound or cobalt compound is provided. Thus, an olefin oligomer having a narrow distribution of the polymerization degree and good properties can be obtained with a high selectivity by using a catalyst capable of being easily handled.
