Abstract

See full text

Certain Group 8-10 transition metal complexes of bidentate ligands can be supported on hydroxyl containing supports which have been treated with certain organometallic compounds. These olefin polymerization catalyst precursors can be activated for olefin polymerization by contacting them with specific types of compounds to form olefin polymerization catalysts. Olefins which may be polymerized include ethylene and certain polar comonomers. The polyolefins produced are useful, for example, as films for packaging and as molding resins.
