Filed:

Dec 29, 1999

Appl. No.:

09/474402

Inventors:

Michael D. Jensen - Bartlesville OK
Kenneth R. Farmer - Dewey OK

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C08F 416

US Classification:

526127, 526133, 526134, 526161, 502162

Abstract:

A process is provided which comprises preparing heterogeneous or homogeneous catalyst systems comprising cyclodisilizane complexes of Group IV metals wherein said metal is selected from consisting of titanium, zirconium and hafnium; and a cocatalyst selected from the group consisting of methylaluminoxane and fluoro organic boron compounds and mixtures thereof. This invention also provides polymerization processes comprising contacting a mono-1-olefin, and optionally one or more higher alpha-olefins, in a reaction zone with cyclodisilizane complexes of Group IV metals catalyst systems and in the presence of a cocatalyst selected from the group consisting of aluminoxane, fluoro organic boron compounds, and mixtures thereof are provided.

International Classification:

B01J 3100

US Classification:

502128, 502119, 502129, 526135, 526160, 526943

Abstract:

This invention provides catalyst compositions that are useful for polymerizing at least one monomer to produce a polymer. This invention also provides catalyst compositions that are useful for polymerizing at least one monomer to produce a polymer, wherein said catalyst composition comprises contacting a organometal compound/organoaluminum mixture, a treated solid oxide compound, and, optionally, a second organoaluminum compound. The solid oxide has been treated with an electron-withdrawing compound, in particular a chlorine, preferably zinc chloride and carbon tetrachloride.
