PROBLEM TO BE SOLVED: To provide a method for producing an olefin oliogomer, by which the oligomer yield of a specific fraction (trimer and/or tetramer) is selectively increased in producing an olefin oliogomer by polymerizing an olefin in the presence of a solid acid catalyst.;SOLUTION: The method for producing an olefin oligomer comprises bringing a raw material olefin into contact with a catalyst prepared by supporting a heteropoly acid on a metal oxide carrier and/or a catalyst containing a heteropoly acid alkali metal salt.;COPYRIGHT: (C)2005,JPO&NCIPI
