Preparation Of Supported Silyl-Capped Silica-Bound Anion Activators And Associated Catalysts
US Patent:
7847038, Dec 7, 2010
Filed:
Jun 23, 2008
Appl. No.:
12/144424
Inventors:
Gary L. Casty - Easton PA, US
George Rodriguez - Houston TX, US
George Rodriguez - Houston TX, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C08F 4/44
US Classification:
526129
Abstract:
A method for the preparation of olefin polymerization catalysts that are the reaction products of the catalytic reaction of surface hydroxyls of a support with a trialkyl silane to afford hydrogen and the corresponding surface bound alkyl silyl ether and at the same time with a strong Lewis acid which support is converted to a silica bound anion that in a second step is fully converted by reaction with QMto the desired catalyst. Catalyst compositions are disclosed herein. Processes disclosed herein include processes for the polymerization of olefinically unsaturated monomers comprising contacting a plurality of one or more of the monomers with the catalyst.

International Classification:
D21H 19/18
US Classification:
524477, 524489, 524491, 524583
Abstract:
Provided are adhesive compositions composed of a polyolefin composition comprising at least about 50 wt. % polypropylene and at least one wax. The polymer compositions have a Dot T-Peel of about 1 Newton or more, a branching index (g′) of 0. 95 or less measured at the Mz of the polymer, a molecular weight of 100,000 or less, and the adhesive compositions has a fast set time. The packaging industry desires adhesive compositions having a fast set time, such as those setting in less than five seconds from a molten state at conventional packaging operating temperatures to a solid or quasi solid having favorable Dot T-Peel, set time, and or fiber tear adhesion properties. Polymer based adhesives performing within this window are a favorable alternative to conventional formulated adhesives. The provided adhesive compositions exhibit a favorable balance of properties such as high adhesive strength, wide temperature operating window, and fast set time.
