A high molecular weight propylene polymer exhibiting high stereoregularity (isotactic) and high position selectivity can be effectively produced by polymerizing at least one monomer selected from propylene, α-olefins and polyenes in the presence of a catalyst for olefin polymerization comprising:
(A) a bridged metallocene compound represented by the General Formula [I] given in claims (diphenylmethylene(3-tert-butyl-5-ethyl-cyclopentadienyl)(fluorenyl)zirconium dichloride, etc.); and
(B) one or more compound(s) selected from
(b-1) an organoaluminumoxy compound
(b-2) a compound which reacts with the bridged metallocene compound (A) to form an ion pair, and
(b-3) an organoaluminum compound.
