Patent number: 4588758Abstract: A tire sealant composition for injection into pneumatic tires is provided. The tire sealant composition promotes heat transfer in a rolling tire, thereby keeping the tire somewhat cooler; it assists in balancing the wheel and tire, thereby prolonging the life of the tire and precluding unnecessary unevenness of wear of the tire; and the tire sealant composition serves to seal the tire around the wheel rim and particularly in the tread area of the tire against punctures. The composition includes a thickener and binding agent, asbestos fibers, ethylene glycol, hydrocarbon process oil, a detergent as a wetting agent and emulsifier, sodium bicarbonate, and water.Type: GrantFiled: March 13, 1985Date of Patent: May 13, 1986Inventor: Lawrence E.

Patent number: 4483957Abstract: The instant invention relates to a process for increasing the viscosity of organic liquids by incorporating in said liquid a minor amount of polymer complex, and 1 to 1000 parts per million by volume of a cosolvent for the ionic groups of said polymer. The polymer complex comprises the reaction product of a metal neutralized sulfonated polymer and a styrene-ring pyridene copolymer, wherein the polymer complex is substantially soluble in said organic liquid, and pendant sulfonate groups which are substantially insoluble in said organic liquid. The cosolvent is selected because it will solubilize the pendant sulfonate groups and provide a reasonably homogeneous mixture of solvent, cosolvent and ionomeric polymer. The preferred compositions prepared by the method of the instant invention comprise an organic liquid having a solubility parameter of from 6 to 10.5 in combination with a polymer complex containing from 0.2 up to 10.Type: GrantFiled: November 14, 1983Date of Patent: November 20, 1984Assignee: Exxon Research & Engineering Co.Inventors: Robert D.
