PCT No. PCT/JP94/00024 Sec. 371 Date Sep. 8, 1994 Sec. 102(e) Date Sep. 8, 1994 PCT Filed Jan. 11, 1994 PCT Pub. No. WO94/16009 PCT Pub. Date Jul. 21, 1994A propylene polymer composition is prepared by mixing a first propylene polymer prepared using an olefin polymerization catalyst containing a specific metallocene catalyst component of formula (I), e.g., rac-dimethylsilylene-bis{1-(2-ethyl-4-phenylindenyl)} zirconium dichloride, and an organoaluminum-oxy cocatalyst, with a second propylene polymer component. The compositions are excellent in heat resistance, mechanical strength, tensile elongation at break, and other properties and can be used to produce various structural materials, sheets and films.
