| titleOfInvention | Olefin polymerization catalyst and process for preparing polyolefins |
| abstract | According to the present invention, there are provided a catalyst and a process for the preparation of polyolefins having a relatively wide molecular weight distribution, good particle properties, a narrow composition distribution in copolymerization and a high molecular weight and being less sticky. The catalyst is prepared by contacting the following constituents (1) to (4) with one another: n (1) a compound represented by the general formula Me 1 R 1 p (OR 2 ) q X 4-p-q , where Me 1 is Zr, Ti or Hf, R 1 and R 2 are each independently a hydrocarbon group having 1 to 24 carbon atoms, X is a halogen atom, p and q are each an integer in the ranges of 0≦p≦4 and 0≦q≦4 , provided 0≦p+q≦4; n (2) a compound represented by the general formula Me 2 R 3 m (OR 4 ) n X 2 z-m-n , where Me 2 is a Group I-III element in the Periodic Table, R 3 and R 4 are each independently a hydrocarbon group having 1 to 24 carbon atoms, X 2 is a halogen atom or a hydrogen atom, provided when X 2 is a hydrogen atom, Me 2 is a Group III element in the Periodic Table, z is the valence of Me 2 , m and n are each an integer in the ranges of 0≦m≦z, and 0≦n≦z, provided 0≦m+n≦z; n (3) an organocyclic compound having conjugated double bonds; and n (4) a modified organoaluminum compound containing Al--O--Al bond, and thereafter contacting the resulting contact reaction product with the following component (5): n (5) an inorganic carrier and/or a particulate polymer carrier. |
