PROCESS FOR THE PREPARATION OF AN ETHYLENE AND alpha -OLEFIN COPOLYMER

摘要

The present process preparing an ethylene/ alpha -olefin copolymer is conducted in the presence of a novel transition metal complex and co-catalyst. The process is further characterizable in that the transition metal complex is a reduced transition metal complex, selectable from groups 4-6 of the Periodic System of the Elements, with a multidentate monoanionic ligand and with two monoanionic ligands, at a temperature of between 100 and 220 DEG C. In particular the reduced transition metal in the complex is titanium (Ti (III)).
