Abstract: A catalyst system comprising a combination of: 1) one or more catalyst compounds comprising at least one oxygen linkage, such as a phenoxide transition metal compound; 2) a support comprising an organosilica material, which may be a mesoporous organosilica material; and 3) an optional activator. Useful catalysts include biphenyl phenol catalysts (BPP). The organosilica material may be a polymer of at least one monomer of Formula [Z1OZ2SiCH2]3 (I), where 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. This invention further relates to processes to polymerize olefins comprising contacting one or more olefins with the above catalyst system.

Abstract: Improved CO2 sorbents comprised of a mesoporous silica functionalized with a polyamine are obtained by the in-situ polymerization of azetidine. Also included herein are processes utilizing the improved CO2 sorbents wherein CO2 is chemisorbed onto the polyamine portion of the sorbent and the process is thermally reversible.
