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', R&#x2032; 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. Polymers produced using the activating supports exhibit improved rheology properties.

Activating supports

A process for the co-oligomerization of 1-dodecene and 1-decene to produce a polyalphaolefin having a kinetic viscosity of 4 to 6 cSt at 100&deg; C., a Noack weight loss of 4 to 9%, a viscosity index of 130 to 145, and a pour point of &minus;60&deg; C. to &minus;50&deg; C.

Co-oligomerization of 1-dodecene and 1-decene

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.

Production of monoolefin oligomer

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. C. and under a pressurized atmosphere of boron trifluoride in the range of 2 to 4 bars gauge until the monoolefin conversion is at least 95% and the combined total of dimer and trimer in the liquid reaction mixture is at least 60% by weight.

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.
