Abstract: Activating supports are prepared by (a) combining (i) fluorine-containing compounds having a reactive group and (ii) an organometallic compound, (b) contacting a porous mineral oxide support material with the mixture from step (a), (c) heating the functionalized support from step (b) under an inert gas and then under an atmosphere comprising oxygen, and (d) recovering the activating support. The fluorine-containing compounds may have the formula R(Fn)-X wherein R is hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl with up to 20 non-hydrogen atoms, n is 1-41, X is OH, SH or NR?2, R? is hydrogen or hydrocarbyl. The activating supports are useful in combination with transition metal catalysts for polymerization of olefins, e.g., with metallocene complexes. Preparation of the activating supports is easier and more economic than prior methods and provides for supported polymerization catalyst systems having excellent activities.

Abstract: Activating supports may be suitably prepared by (a) combining (i) fluorine-containing compounds having a reactive group and (ii) an organometallic compound, (b) addition of a porous mineral oxide support material, (c) heating the functionalized support from step (b) under an inert gas and then under an atmosphere comprising oxygen, and (d) recovering the activating support. The preferred fluorine-containing compounds have the formula: R(Fn)-X wherein R is hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl with up to 20 non-hydrogen atoms, n is 1-41, X is OH, SH or NR?2, R? is hydrogen or hydrocarbyl. The activating supports are suitable used in combination with transition metal catalysts for the polymerization of olefins. The supports are most preferable used in combination with metallocene complexes.

Abstract: An olefin polymerization process comprises gas-phase polymerization of at least one olefin monomer in more than one polymerization zones using a high activity Ziegler-Natta catalyst system comprising a solid, magnesium-supported, titanium-containing component and an aluminum alkyl component comprising introducing the titanium-containing component and an aluminum alkyl component into the first polymerization zone and then introducing additional aluminum alkyl component into a subsequent polymerization zone without added titanium-containing component.

Abstract: A monoolefin oligomerization process which gives high yields of diner and trimer at high monoolefin conversions in a single stage reaction is described. The process involves contacting a C.sub.6-20 oligomerizable olefin with a catalyst comprising boron trifluoride and from 0.05 to 2.5 mol %, based on the total quantity of monoolefin being used, of an alcohol catalyst promoter which is added portionwise during the oligomerization. The oligomerization is performed at a temperature of 45-90.degree. C. and under a pressurized atmosphere of boron trifluoride until the monoolefin conversion is at least 90% and the combined total of dimer and trimer in the liquid reaction mixture is at least 70% by weight.

Abstract: A monoolefin oligomerization process which gives high yields of dimer and trimer at high monoolefin conversions in a single stage reaction is described. The process involves contacting a C.sub.6-20 vinyl olefin with a catalyst comprising boron trifluoride and from 0.075 to 0.5 mol %, based on the total quantity of monoolefin being used, of an alcohol catalyst promoter. The oligomerization is performed at a temperature below about 40.degree.

Abstract: Described is a process for isomerizing .alpha.-olefin to produce olefinic oil having a viscosity at 100.degree. C. of no more than about 1.6 cSt, a viscosity at 40.degree. C. of no more than about 3.8 cSt, and a pour point of 0.degree. C. or lower, preferably -10.degree. C. or lower. The process comprises contacting the .alpha.-olefin having from about 14 to about 20 carbon atoms with a catalytic quantity of nonmetallic sulfonic or perfluorosulfonic acid resin catalyst under identified isomerization conditions, thereby producing deep internal olefin having the desired combination of physical properties.
