    摘要: A catalyst system for the polymerization of olefins which includes a solid catalyst component and a cocatalyst. The solid catalyst component includes the contact product of silica, an alkyl magnesium-containing species, a compound having the structural formula E(YZ)mX4-m, where E is an atom of an element of Group 14 of the Periodic Table of the Elements; Y is an atom of an element of Group 16 of the Periodic Table of the Elements; Z is hydrogen, hydrocarbyl or mixtures thereof; X is hydrogen, halogen, hydrocarbyl or mixtures thereof; and m is an integer of 1 to 4 and a tetravalent titanium compound. The cocatalyst includes a mixture of at least two compounds having the structural formula AlRxX13-x, where R is the same or different and is hydrocarbyl; X1 is halogen; and x is an integer of 1 to 3 with the proviso that at least one of the compounds is defined by x being 3 and at least one of the compounds as defined by x being 1 or 2.

    摘要: 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.

    摘要: A vanadium-containing catalyst system particularly suited to the polymerization of olefin polymers. The catalyst system includes a supported, first catalyst component prepared by contacting silica with hexaalkyldisilazane and thereupon 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 13 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 washed and then 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.
