International Classification:

C08K 524

US Classification:

524262, 524526, 152450

Abstract:

The invention relates to a tire with a tread. The tread is composed of at least two defined elastomers having Tgs spaced apart by at least 55Â C. to the exclusion of elastomers having Tgs between -30Â and -85Â C. The tread composition can be reinforced with either carbon black or a combination of carbon black and silica reinforcing fillers.

International Classification:

C08K 3/34

US Classification:

524445, 524492, 524493, 524495

Abstract:

This invention relates to preparation of nanocomposites comprised of elastomer and a dispersion of an at least partially exfoliated water swellable clay and to rubber compositions containing such nanocomposite and articles of manufacture which contain at least one component thereof. The nanocomposite is prepared by addition of a water suspension of water swellable clay particles to an anionic aqueous emulsion of elastomer particles to form a mixture to which an amine having at least two amine centers is added to intercalate and at least partially exfoliate the water swelled clay particles by an ion exchange within the galleries of the multilayered clay with cation exchangeable ion(s) and to aid in coagulating the elastomer and resultant clay particles to form said nanocomposite.

C08F 136/06
C08C 19/00

US Classification:

524493, 1522095, 5263404

Abstract:

This invention relates to a silica reinforcement-containing rubber composition which contains a functionalized polybutadiene rubber to promote a relatively low hysteretic loss to thereby enhance its desirability for tire sidewall and subtread applications in a sense of advantageously promoting reduced tire rolling resistance without significantly compromising various other desirable tire performance parameters.

International Classification:

B29C 73/16
B29D 30/06

US Classification:

152502, 2643283, 264 3614

Abstract:

The present invention is directed to self-healing materials and use thereof for extending the lifespan of a tire. The self-healing material includes a rubber healing agent, e.g., sulfur, encapsulated by a coating material, e.g., polypropylene, defining a microcapsule. The self-healing materials are processed with rubbery polymers to provide a rubber compound suitable for use in a tire. The microcapsule coating material is selected to prevent release of the healing agent during the processing steps of the rubber compound, such as can occur through melting or softening of the coating material, and to release the healing agent, e.g., via melting or softening, at a desired temperature greater than a tire's running temperature. Release of the healing agent can help repair damage to local polymeric structure, such as broken cross-links, by reacting with the surrounding rubber. In this way, that area of the rubber compound can be reinforced, thereby prolonging the life of the tire.

Inventors:

Ramendra Nath Majumdar - Hudson OH, US
William Paul Francik - Bath OH, US

International Classification:

B60C 5/12
B29D 30/24

US Classification:

152510, 264263

Abstract:

The present invention relates to a pneumatic tire having an air barrier layer, particularly an integral pneumatic tire innerliner, for prevention, or retardation, of air permeation from its inner chamber to the atmosphere through the carcass of the tire. The innerliner is comprised of an annular, cylindrical, hoop of a film having its ends overlapped and heat sealed together. The film is comprised of a continuous thermoplastic polymer phase which contains a dispersion therein of cured rubber domains, particularly cured low unsaturation rubber domains. In one embodiment, one surface of the film contains a thin bonding layer to aid in bonding the film to an unsaturated rubber-containing tire carcass. In one embodiment, the overlapping portion of the ends of the film have a thin rubber layer positioned therebetween.
