A PROCESS FOR MAKING POLYOLEFINS HAVING BROAD MOLECULAR WEIGHT DISTRIBUTIONS

摘要

A process for producing polyolefin resins with a broad molecular weight distribution comprising reacting one or more olefins in the presence of a reduced transition metal complex and a co-catalyst. The transition metal complex consists of a reduced transition metal, chosen from groups 4-6 of the Periodic Table of the Elements, with a multidentate monoanionic ligand and with two monoanionic ligands. In particular the reduced transition metal is preferably titanium (Ti).
