    摘要： 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 Me¹R¹ p (OR) q X 4-p-q , where Me¹ is Zr, Ti or Hf, R¹ and R 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 MeR³ m (OR⁴) n X z-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, X is a halogen atom or a hydrogen atom, provided when X is a hydrogen atom, Me is a Group III element in the Periodic Table, z is the valence of Me, 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 A1-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.
