Patent number: 6255387Abstract: A derivatized blend and a process for producing that blend in which a high ethylene content ethylene-propylene polymer and a lower ethylene content ethylene-propylene polymer are subjected to simultaneous blending and shearing to reduce their molecular weights and molecular weight distribution and then reacted with an organic compound to derivatize the blend. The sheared derivatized blend of polymers can function as a shear stable multifunctional viscosity index improver with improved low temperature properties and, in some cases, dispersancy antioxidant and anti-wear properties.Type: GrantFiled: January 8, 1998Date of Patent: July 3, 2001Assignee: Ethyl Additives CorporationInventors: Errol J. Olivier, Robert T. Patterson, Peter N. Nugara

Patent number: 5525668Abstract: Novel thermoplastic elastomer compositions, made by dispersing a polyolefin elastomer phase containing functionalized EPM or EPDM in a polyamide resin followed by cross-linking of the elastomer phase, are described. The cross-linked phase exists as discreet particles, providing an overall blend which remains thermoplastic. The resulting blend may be used in the fabrication of elastomeric goods without the need for a separate vulcanization step after the desired object is formed.Type: GrantFiled: December 6, 1994Date of Patent: June 11, 1996Assignee: DSM Copolymer, Inc.Inventor: Errol J. Olivier
