PURPOSE:To produce a polyolefin in a high yield, by polymerizing an olefin in the presence of a catalyst comprising a specific transition metal catalyst and an organometallic compound of Groups I-III of the periodic table. CONSTITUTION:A magnesium halide of formula III obtained by the reaction of a Grignard reagent of formula I (wherein R<1> is a hydrocarbon residue; X<1> is Br or I; X<2> is Cl; and l is 0-1) with thionyl chloride, and an oxygen- containing organic compound (e.g., phosphates) are ground together, and contacted with a titanium halide (e.g., TiCl4) to obtain a transition metal catalyst. Then, in the presence of a catalyst comprising the transition metal catalyst and an organic compound of a metal of Groups I-III of the periodic table (e.g., triethylaluminum), an olefin is (co)polymerized.
