Abstract:
A catalyst composition adapted for the polymerization of ethylene, comprising a complex of CO(II) or CO(III) with one molecule of a tridentate ligand selected from the group consisting of a 2,6-pyridinecarbox-aldehydebis(imine) and a 2,6-diacylpyridinebis(imine), in which the tridentate ligand causes steric crowding about the CO(II) or Co(III), and in which the CO(II) or CO(III) also has (i) an empty coordination site or bonded to it a ligand that may be displaced by ethylene, and (ii) bonded to it a ligand that may add to ethylene.
