摘要： A method of producing a tire including mixing in a non-productive phase at least one elastomer with a polyamide having a melting temperature of less than 180° C. The polyamide is allowed to heat to at least its melting temperature. During the productive phase, at least one curing agent is added to the elastomeric composition. The curing agent may be a sulfur containing curing agent and/or a non-sulfur containing curing agent. The elastomeric composition may optionally include a crystalline EPDM elastomer.

摘要： The present invention is directed towards speckled tire treads for tires. Specifically, the speckled tire tread includes a primary tread compound that serves as a matrix in which is distributed discrete particles of one or more secondary tread compounds, at least one of the compounds is a different color than the other tread compound(s) so as to be visually distinguishable. For example, the primary tread compound may include carbon black pigment and be black in color while the secondary tread compound can include one or more pigments to provide the particles with non-black color. Thus, the colored particles have a visually distinguishable color from that of the primary tread composition. Additionally, at least a portion of the particles may be situated for viewing on a running surface of the tire tread so that a subject can visually distinguish between the compounds, and such observed compounds may provide a different tire performance characteristic(s).

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.
