COPOLYMERIZATION OF OLEFINS

Title:

COPOLYMERIZATION OF OLEFINS

Document Type and Number:

WIPO Patent Application WO1999062967

Kind Code:

A3

Abstract:

Ethylene and/or propylene, and alpha -olefins may be copolymerized by contacting them with certain iron or cobalt complexes of selected 2,6-pyridinecarboxaldehydebis(imines) and 2,6-diacylpyridinebis(imines). The polymers produced, some of which are novel, are useful as molding resins.
