OLEFIN POLYMERIZATION PROCESS WITH AN ORGANOMETALLIC COMPLEXCOMPRISING AN INDENOINDOLYL LIGAND ON A MAGNESIUM CHLORIDE-ALCOHOL SUPPORT

摘要

A process for polymerizing ethylene is disclosed. A magnesium chloride-alcohol is used to support an organometallic complex comprising a Group 3 to 10 transition metal and an indenoindolyl ligand. The supported organometallic complex is mixed with an activator and ethylene and the ethylene is polymerized. Use of magnesium chloride containing an alcohol as the support provides an unexpected boost in catalyst activity and improves polymer rheological properties.
