Patent number: 5948835Abstract: Disclosed are elastomeric compounds including an elastomer and a silicon-treated carbon black, and optionally including a coupling agent. The elastomeric compound exhibits poorer abrasion resistance, lower hysteresis at high temperature and comparable or increased hysteresis at low temperature compared to an elastomer containing an untreated carbon black. A variety of elastomers and formulations employing such elastomers are contemplated and disclosed. Elastomeric compounds incorporating an elastomer and an oxidized, silicon-treated carbon black are also disclosed. Also disclosed is method for preparing elastomers compounded with the treated carbon black.Type: GrantFiled: June 18, 1997Date of Patent: September 7, 1999Assignee: Cabot CorporationInventors: Khaled Mahmud, Meng-Jiao Wang, Robert A.

Patent number: 5939478Abstract: The viscosity of a solvent is modified by thickening the solvent with a silicone latex. A silicone latex having a plurality of crosslinked polysiloxane particles is first prepared by mixing the siloxane polymer, a surfactant, and water; emulsifying the mixture to a gel phase; diluting the emulsion with water; adding a cure package (i.e., a catalyst, a crosslinker, or both, or a self catalytic crosslinker); and then without removing the water from the latex and after the particles of siloxane polymer in the latex have been cured, mixing the latex and solvent to thicken the solvent, forming viscous liquids, gels, and pastes. Water in the latex thickened solvent composition can be stabilized by adding a silicone polyether during mixing of the latex and the solvent.Type: GrantFiled: November 13, 1997Date of Patent: August 17, 1999Assignee: Dow Corning CorporationInventors: James Anderson Beck, Vicky Sue Cobb, Cassie Emelia Cuthbert, Eric Jude Joffre, Virginia Kay O'Neil, Burt Michael Wrolson
