    • A multiple site solid catalyst component capable of producing polyolefins having a broad or multimodal molecular weight distribution, such as a bimodal molecular weight distribution, is prepared by contacting a particulate solid support with a zirconium compound or complex to bind the zirconium compound or complex to the support, optionally followed by contacting the supported zirconium compound or complex with a Lewis acid to produce an intermediate product, optionally isolating and washing the supported zirconium compound or complex or resulting intermediate product to remove soluble by-products therefrom, and reacting the washed or unwashed supported zirconium compound or complex or intermediate product with a titanium or vanadium compound to produce a solid catalyst component.

    • A vanadium-containing catalyst system particularly suited to the polymerization of blow moldable olefin polymers. The catalyst system includes a supported, first catalyst component prepared by contacting preheated silica, with (1) a compound or complex which includes at least one carbon to magnesium covalent bond and (2) a compound which includes at least one carbon to Group III metal covalent bond. The sequence of contact of the silica with compound or complex (1) and compound (2) is optional. However, unless the compound or complex (1) and the compound (2) contact the silica simultaneously, the product of this contact is next contacted with whichever of compound (1) or (2) does not initially contact the silica. The product of the step of contacting with compounds (1) and (2) is contacted with a vanadium compound which includes at least one halogen atom. Finally, the product of the vanadium compound contacting step is contacted with an alcohol. A second component of the catalyst system is an organoaluminum compound cocatalyst. The catalyst system also includes a halocarbon compound promoter as a third catalyst component.
    • 一种特别适用于可吹塑烯烃聚合物聚合的含钒催化剂体系。 催化剂体系包括通过使预热的二氧化硅与(1)包含至少一个碳 - 镁共价键的化合物或络合物接触而制备的负载的第一催化剂组分和(2)包含至少一个碳至III族金属的化合物 共价键。 二氧化硅与化合物或络合物(1)和化合物(2)的接触顺序是任选的。 然而,除非化合物或络合物(1)和化合物(2)同时与二氧化硅接触,否则接触的产物接下来与化合物(1)或(2)中最初不接触二氧化硅的化合物接触。 与化合物(1)和(2)接触的步骤的产物与包含至少一个卤素原子的钒化合物接触。 最后,将钒化合物接触步骤的产物与醇接触。 催化剂体系的第二个组分是有机铝化合物助催化剂。 催化剂体系还包括作为第三催化剂组分的卤代烃化合物促进剂。
