An object of this invention is to provide a polymerization catalyst that can be used for the polymerization of olefins. Another object of this invention is to present a method of producing excellent olefin polymers with high copolymerization properties and high molecular weight using the polymerization catalyst. The catalyst of this invention is an olefin polymerization catalyst which contains a reaction product obtained from vanadium oxytrichloride and 2,2'-thiobis(6-5-butyl-4-methylphenyl), an organic aluminum compound, such as trimethylaluminum, and an ionized ionic compound, such as N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate, and the like. By using this catalyst to polymerize ethylene with an α-olefin, such as propylene, 1-heptene, 1-octene, and the like., or a non-conjugated diene, such as 5-ethylidene-2-norbornene, and the like., a polymer of high copolymerization properties can be obtained.
