摘要： The present invention relates to a pneumatic tire with a built-in sealant layer comprised of a depolymerized butyl rubber based sealant precursor. The butyl rubber of the built-in sealant precursor composition is depolymerized in situ within the tire with an activated free radical generating organoperoxide. The organoperoxide is activated with a 2,2,6,6-tetra alkyl piperidine hindered amine. Representative of such hindered amines are, for example, a poly[[6-[1,1,3,3,-tetramethylbutyl)amino]-s-triazine-2,4-diyl][2,2,6,6,-tetramethyl-4-piperidyl)imino]hexamethylene[(2,2,6,6-tetramethyl-4-piperidyl)imino]] compound. The sealant layer, if desired, may be of a color which contrasts with black. For such purpose the sealant layer may contain a colorant of a non-black color to a substantial exclusion of carbon black. The butyl rubber-based sealant precursor is built into the tire as a layer to form a tire assembly wherein the butyl rubber-based composite portion of the sealant precursor layer is at least partially depolymerized by a said activated organoperoxide during a subsequent curing of the tire at an elevated temperature in a suitable mold to form the tire having the resultant built-in sealant layer. The sealant composition may additionally contain conventional clay, exfoliated intercalated clay platelets and/or calcium carbonate.

摘要： The present invention provides for oxygen scavenging materials and uses thereof for reducing oxygen content in an air cavity of a mounted tire, such as to reduce oxidation of a tire. The oxygen scavenging material can include a metal or metal-based material, an antioxidant, or microorganism. In one example, the oxygen scavenging material may be situated or secured within a tire cavity or secured to the tire rim of a wheel prior to mounting of the tire on the rim. Accordingly, the tire is mounted on the tire rim to define an air cavity with the oxygen scavenging material being located therein. The air cavity is be filled with air comprising oxygen to a desired internal air pressure with the oxygen scavenging material being provided in an amount sufficient for reducing oxygen content in the air cavity, such as to reduce oxidation of the tire thereby increasing the lifespan thereof.
