Patent number: 7833585Abstract: A hyperbranched polymer having pendent olefinic groups and comprising polymer units derived from one or more terminally-unsaturated, acyclic aliphatic diene and polymer units derived from maleic anhydride. Optionally, the hyperbranched polymer may further comprise polymer units derived from one or more 1-alkenes and/or a chain transfer agent. A process to prepare the hyperbranched polymer comprises contacting maleic anhydride with at least one terminally unsaturated acyclic aliphatic diene having at least 7 carbon atoms in the presence of an effective amount of a radical initiator in an aprotic solvent under dilute conditions.Type: GrantFiled: July 15, 2009Date of Patent: November 16, 2010Assignee: E.I. du Pont de Nemours and CompanyInventors: Stephen Ernest Jacobson, Patricia Metzger Cotts

Patent number: 6620895Abstract: Polyethylenes made from ethylene and a series of &agr;-olefins using a catalyst that copolymerizes ethylene and &agr;-olefins usually have excellent melt processing characteristics, especially in uses where high zero shear viscosity and low high shear viscosity are desirable. These polyethylenes are preferably made by forming the &agr;-olefins in situ from ethylene during the polymerization process. The polyethylenes are especially useful in blow molding, extrusion or extruded blown film processes.Type: GrantFiled: September 28, 2000Date of Patent: September 16, 2003Assignee: E. I. du Pont de Nemours and CompanyInventors: Patricia Metzger Cotts, William Howard Tuminello, Lin Wang, Joel David Citron
