PROCESSES FOR THE PREPARATION POLYOLEFIN RESINS USING SUPPORTED IONIC CATALYSTS

摘要

This invention relates to olefin polymerization processes suitable for limiting or eliminating aromatic solvents or diluents. The invention process es can be conducted by contacting polymerizable olefin monomers with catalyst complexes of Group 3-11 metal cations and noncoordinating or weakly coordinating anions bound directly to the surfaces of finely divided substra te particles or to polymer chains capable of effective suspension or solvation in polymerization solvents or diluents under polmerization conditions. These processes minimize problems associated with using largely insoluble organometallic or organometalloid catalysts and cocatalysts in aliphatic, solution, or diluent polymerization processes.
