    摘要: An object of the present invention is to provide polyethylene having excellent moldability and impact resistance and excellent balance between rigidity and durability, produced using a novel organoaluminum compound-supported chromium catalyst, a method for producing polyethylene, and a hollow plastic molding containing the polyethylene. The polyethylene of the invention is polymerized using a chromium catalyst, and has a weight average molecular weight (Mw) of 30,000 or more at the maximum value in a branching degree distribution curve that shows a molecular weight dependency of short chain branches having 4 or more carbon atoms.

    摘要: The present invention relates to an olefin polymerisation catalyst obtainable by depositing on a dry inorganic oxide support a mononuclear chromium complex which is a mixture of (A) a first mononuclear chromium complex represented by the general formula:
    wherein
    - three of R₁ to R₅ are H and the other two are H, or C₁-3 hydrocarbyl group, and
    - L is one or more hydrocarbyl ligands which are sufficiently reactive to enable the complex to react with the inorganic oxide without thermal activation, and
    (B) a second mononuclear chromium complex representable by the general formula:
    wherein
    - the cyclopentadienyl ligand is substituted with 4 or 5 hydrocarbyl groups (R1-R5) containing 1 to 3 carbon atoms, and
    - L has the same definition as above, being identical or different.
    The catalyst can be used for polymerising olefins, particularly ethylene optionally with C₃-8 alpha-olefins. It can be thermally activated before use in olefin polymerisation. It produces polyolefins having a relatively broad molecular weight distribution, the breadth and shape of which being easily controlled.
