Olefin polymerization catalyst system comprising mesoporous organosilica support
First Claim
1. A catalyst system comprising:
- (1) one or more olefin polymerization catalyst compounds comprising a nitrogen linkage to a Group 3-12 transition metal or a Group 13 or 14 main group metal;
(2) a catalyst support comprising an organosilica material that is a polymer of at least one monomer of Formula [Z1OZ2SiCH2]3 (I), wherein Z1 represents a hydrogen atom, a C1-C4 alkyl group, or a bond to a silicon atom of another monomer and Z2 represents a hydroxyl group, a C1-C4 alkoxy group, a C1-C6 alkyl group, or an oxygen atom bonded to a silicon atom of another monomer; and
(3) an optional activator.

Abstract
A catalyst system comprising a combination of: 1) one or more catalyst compounds comprising at least one nitrogen linkage; 2) a support comprising an organosilica material, which is a mesoporous organosilica material; and 3) an optional activator. Useful catalysts include pyridyldiamido transition metal complexes, HN5 compounds, and bis(imino)pyridyl complexes. The organosilica material is a polymer of at least one monomer of Formula [Z1OZ2SiCH2]3(1), where Z1 represents a hydrogen atom, a C1-C4alkyl group, or a bond to a silicon atom of another monomer and Z2 represents a hydroxyl group, a C1-C4alkoxy group, a C1-C6 alkyl group, or an oxygen atom bonded to a silicon atom of another monomer. This invention further relates to processes to polymerize olefins comprising contacting one or more olefins with the above catalyst system.
