There is disclosed a pneumatic tire having a rubberized component comprising:

Pneumatic tire having a rubber component containing a dendrimer

Rubber compositions containing preciptated organosilicon particles having a core and a shell

Rubber compositions containing silicon coupled oligomers

A pneumatic tire having a tread comprised of (a) a diene-based elastomer containing olefinic unsaturation and (b) from 1 to 150 phr of a metal oxide aerogel.

Pneumatic tire having a tread containing a metal oxide aerogel

Method for the preparation of a diene polymer interpenetrated with a polysiloxane

The present invention relates to a rubber composition comprising (A) an elastomer containing olefinic unsaturation and (B) 35 to 110 phr of silica filler, wherein said silica filler is comprised of (i) 10 to 100 phr of a first silica having a pore size distribution maximum of the aggregates in the first silica ranging from greater than 55 to 400 nm as determined by mercury porosimetry and an average specific surface area ranging from 60 to 135 m /g as determined by N adsorption; and (ii) 10 to 100 phr of a second silica having a pore size distribution maximum of the aggregates in the second silica ranging from 5 to 50 nm as determined by mercury porosimetry and an average specific surface area ranging from 140 to 250 m /g as determined by N adsorption.

Rubber composition containing two silicas

There is disclosed a rubber composition particularly suited for use in tires. The rubber composition is composed of 100 parts by weight of at least one rubber containing olefinic unsaturation; and from 1 to 150 parts per 100 parts by weight of rubber, of a silica having predispersed on the surface of the silica a liquid epoxidized butadiene polymer having a number average molecular weight of from 500 to 10,000.

Asymmetrical siloxy compounds

This invention relates to preparation of an elastomer which contains a dispersion of silica reinforcement by forming a silica reinforcement in situ within an unvulcanized elastomer host, the resulting elastomer/filler composite and tire having component which contains such reinforced elastomer. The invention includes a rubber composition of at least two elastomers wherein one of said elastomers is a pre-formed composite of elastomer/in situ formed silica reinforcement. A tire having a component of such rubber composition, particularly a tire tread, is specifically contemplated.

Preparation of elastomer reinforced with in situ formed silica and tire having component thereof

A rubber composition which contains substantially hollow, irregularly-shaped particles, and/or fragments thereof derived from a surface-modified carbon black aggregate from the which the carbon black core has been removed. For example, an irregularly-shaped carbon black aggregate may be surface-modified to have interconnecting domains of at least one inorganic material on its surface and the carbon black core removed by an oxidation process leaving an irregularly-shaped, substantially hollow particle and/or fragments thereof of said inorganic materials. An article having a component of such rubber composition is also provided such as, for example, a tire or an industrial product.

Rubber composition which contains irregular-shaped hollow inorganic particles and article having component thereof

The present invention relates to rubber compositions containing borate compounds of the formula

Rubber compositions containing borate compounds

The present invention relates to asymmetrical siloxy compounds of the formula

A method of preparing a pre-formed elastomer/filler composite of a diene-based elastomer and particulate filler dispersed therein by polymerizing monomers in the presence of said filler with a polymerization promoting catalyst in which at least a portion of said catalyst is pre-deposited on said filler. Such pre-formed elastomer composite is also contemplated as well as a rubber composition comprised of a blend of such pre-formed composite and at least one additional elastomer. Such filler may be, for example, precipitated silica, carbon black and/or a modified carbon black. A tire having a component of such composite or rubber composition such as, for example a tread, is also provided.
