POLYMERIZATION OF OLEFINS

Title:

POLYMERIZATION OF OLEFINS

Document Type and Number:

WIPO Patent Application WO2001072854

Kind Code:

A3

Abstract:

Transition metal complexes of a monoanionic ligand derived from a selected o-(arylamino)benzalimine, and optionally in the presence of other cocatalysts, polymerize olefins. The resulting polymers are useful as elastomers and molding resins. Novel o-(arylamino)benzalimines and a method of making them are also disclosed.
