Abstract

DC60 (03/06/42) Polyolefin composites may be made by direct polymerization, preferably simultaneous polymerization of one or more polymerizable olefins using a catalyst system of active polymerization consisting of a transition metal, one of which is nickel, forming a complex with a selected ligand. The resulting polyolefin products may have varying molecular weight, molecular weight distribution, crystallinity, or other factors, and would be useful as molding resins and for filmmaking. Polyolefin composites may be made by direct polymerization, preferably simultaneous polymerization of one or more polymerizable olefins using a catalyst system of active polymerization. An active transition metal, one containing nickel complexed with a selected ligand, forms a polyolefin product. This polymer may vary in molecular weight, molecular weight distribution, crystallinity, or other factors, and would be useful as a molding resin and for filmmaking.
