POLYMERIC SUPPORTED CATALYSTS FOR OLEFIN POLYMERIZATION

摘要

The described invention provides a low fouling, high particle density polymerization process and an olefin polymerization catalyst composition comprising the reaction product of a) a polymeric support i) having a surface area of from about 1 to 400 m2/g and ii) functionalized with an acidic protoncontaining ammonium salt of a non-coordinating anion, and b) an organometallic transition metal compound having ancillary ligands, at least one labile ligand capable of abstraction by protonation by said ammonium salt and at least one labile ligand into which an olefinic monomer can insert for polymerization. In a preferred embodiment, the polymeric support has a surface area of 10 m2/g and is particularly suitable for use with high activity organometallic, transition metal catalyst compounds.
