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: (1) a compound represented by the general formula Me1R1p(OR2)qX4-p-q, where Me1 is Zr, Ti or Hf, R1 and R2 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; (2) a compound represented by the general formula Me2R3m(OR4)nX2z-m-n, where Me is a Group I-III element in the Periodic Table, R3 and R4 are each independently a hydrocarbon group having 1 to 24 carbon atoms, X2 is a halogen atom or a hydrogen atom, provided when X2 is a hydrogen atom, Me is a Group III element in the Periodic Table, z is the valence of Me2 , m and n are each an integer in the ranges of 0 ? m ? z, and 0 ? n ? z, provided 0 ? m+n ? z; (3) an organocyclic compound having conjugated double bonds; and (4) a modified organoaluminum compound containing Al-O-Al bond, and thereafter contacting the resulting contact reaction product with the following component (5): (5) an inorganic carrier and/or a particulate polymer carrier. |
