Patent number: 7932346Abstract: A novel process is used to prepare synthetic rubbers (B) which feature very narrow molecular weight distribution and a correspondingly low value for the polydispersity index. The preparation process encompasses the treatment of a synthetic rubber with ultrasound, where the resultant synthetic rubber (B) has a lower weight-average molecular weight (Mw) than the synthetic rubber (A) used. The resultant synthetic rubbers (B) have excellent suitability for processing via extruder processes or injection-molding processes.Type: GrantFiled: June 7, 2010Date of Patent: April 26, 2011Assignee: LANXESS Deutschland GmbHInventors: Lothar Reif, Stephen Pask

Patent number: 7884149Abstract: A nanocomposite material suitable for electrical insulation includes a polymer compounded with a substantially homogeneously distributed functionalized nanoparticle filler. The nanocomposite material is produced by compounding the polymer with the functionalized nanoparticle filler by imparting a shear force to a mixture of the polymer and filler capable of preventing agglomeration of the filler whereby the filler is substantially homogeneously distributed in the nanocomposite material. The electrical insulation may be adapted for AC or DC high voltage, and may also be adapted for low or medium voltage to prevent formation of water tree structures.Type: GrantFiled: July 17, 2009Date of Patent: February 8, 2011Assignee: Rensselaer Polytechnic Institute, Inc.Inventors: John Keith Nelson, Walter Zenger, Robert John Keefe, Linda Sue Schadler Feist
