Patent number: 4814310Abstract: This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the gas phase polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 6 to about 10 percent by weight adsorbed water as the catalyst support material. It has been found that such silica gel may be safely added to an aluminum trialkyl solution to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane component of the catalyst system. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dried to free flowing powder. The dry free flowing powder may then be used as a supported metalllocene alumoxane catalyst complex for gas phase polymerization of olefins.Type: GrantFiled: December 17, 1987Date of Patent: March 21, 1989Assignee: Exxon Chemical Patents Inc.Inventor: Main Chang

Patent number: 4452912Abstract: The invention relates to a process for producing a magnesium-containing supported catalyst for the polymerization and copolymerization of .alpha.-olefins. The magnesium is bound via oxygen to a porous metal oxide; e.g. silicon dioxide and/or aluminum oxide, and has alkoxy groups. This solid is reacted with a transition metal compound and one or more organometallic compounds of Groups I to III of the Periodic Table are added.Type: GrantFiled: November 15, 1982Date of Patent: June 5, 1984Assignee: Ruhrchemie AktiengesellschaftInventors: Mufit Bahadir, Wolfgang Payer

Patent number: 4450098Abstract: Process for preparing and treating a chromium-containing catalyst so that when the catalyst is activated the risk of explosion is substantially reduced. The catalyst comprises a complex of chromium and optionally other transition metal complexes reacted with one or more organometallic compounds of a metal of group II or III of the periodic table, which metal contains hydrocarbyl groups of 1-20 carbon atoms. The reaction product is applied to an inert inorganic support to form the catalyst component which is deactivated by treatment with oxygen or an alcohol to modify or replace residual hydrocarbyl groups. The catalyst component may be activated to form the catalyst by heating in the range 200.degree.-1200.degree. C. The catalyst is used to catalyze a polymerization of alpha-olefins.Type: GrantFiled: August 5, 1982Date of Patent: May 22, 1984Assignee: Stamicarbon B.V.Inventors: Lambertus J. M.

Patent number: 4435519Abstract: Vanadium compound/organometallic compound/inorganic oxide catalyst compositions useful for the polymerization of ethylene to polymers having a molecular weight distribution that can be controlled by selection of the appropriate member of a particular family of vanadium compounds are obtained by using, as the vanadium component, at least one vanadium compound prepared by reacting one molar proportion of VOCl.sub.3 and/or VOBr.sub.3 with about 0.5 to 1 molar proportion of a diol corresponding to the formula HO-R-OH, wherein R is a divalent hydrocarbon radical having a chain length of 2 to 16 carbon atoms. The molecular weight distributions of polymers formed in the presence of the catalyst compositions are narrowed as the chain length of R is increased.
