Patent number: 6153716Abstract: The present invention provides polymers of ethylene having ethyl branches, a narrow molecular weight distribution, no substantial amount of branches longer than any comonomer employed in the polymerization, and an unusually low branching to density ratio. In one embodiment the polyethylenes are substantially free of any branches having more than 2 carbon atoms, i.e. ethyl branches, and the molar percent of ethyl branches is substantially the same for molecular fractions across the molecular weight distribution. In another embodiment the polyethylenes have other branches having 3 or more carbons and the molar percent of the ethyl branches is substantially the same for molecular fractions across the molecular weight distribution.Type: GrantFiled: December 2, 1998Date of Patent: November 28, 2000Assignee: Phillips Petroleum CompanyInventors: M.
