COPOLYMERS OF ETHYLENE WITH VARIOUS NORBORNENE DERIVATIVES

Title:

COPOLYMERS OF ETHYLENE WITH VARIOUS NORBORNENE DERIVATIVES

Document Type and Number:

WIPO Patent Application WO2003031485

Kind Code:

A3

Abstract:

Ethylene and norbornene-type monomers are efficiently copolymerized by certain metal complexes, particularly nickel complexes, containing selected anionic and neutral bidentate ligands. The polymerization process is tolerant of polar functionality on the norbornene-type monomer and can be carried out at elevated temperatures.
