The invention relates to rubber comprised of a reaction product of at least one diene-based elastomer, branched polyethylenimine oligomer and filler reinforcement comprised of at least one of rubber reinforcing carbon black and precipitated silica. The invention further relates to a tire with a component comprised of such rubber composition.

Rubber comprised of product of diene-based elastomer, branched polyethylenimine oligomer and reinforcing filler, and tire with component

There is disclosed a vulcanizable rubber composition comprising: (A) a diene based elastomer, (B) from 50 to 150 parts by weight, per 100 parts by weight of elastomer (phr), of silica; (C) from 0.15 to 0.45 phr of a polymeric amine comprising a primary amine functionality; and (D) from 1.5 to 2.5 parts by weight, per 1 part by weight of the polymeric amine, of an aromatic carboxylic acid or aromatic acid anhydride.

Rubber composition and pneumatic tire

This invention relates to a tire having a rubber component, such as a tread. with filler reinforcement containing surface modified graphene and precipitated silica which may be or may include pre-hydrophobated precipitated silica.

Tire with rubber component containing reinforcement comprised of precipitated silica and functionalized graphene

This invention relates to a rubber composition comprised of at least one conjugated diene-based elastomer containing triglyceride based algae oil and to a tire with a component thereof.

Rubber composition containing algae oil and tire with component

This invention relates to a tire having a rubber tread containing functionalized carbon nanotubes and particulate reinforcement comprised of precipitated silica.

Tire with rubber tread containing precipitated silica and functionalized carbon nanotubes

The invention relates to preparation of rubber reinforced with at least one of graphene and carbon nanotubes with specialized coupling agent and tire with component thereof.

Preparation of rubber reinforced with at least one of graphene and carbon nanotubes with specialized coupling agent and tire with component

This invention relates to a rubber composition comprised of diene-based elastomer, precipitated silica and nano-scale exfoliated graphene platelets. A tire is provided having a component comprised of such rubber composition.

Tire with component comprised of rubber composition containing silica and graphene platelet reinforcement

There is disclosed a vulcanizable rubber composition comprising: where R, Rand Rare independently C1 to C8 alkyl or C1 to C8 alkoxy, with the proviso that at least two of R, Rand Rare C1 to C8 alkoxy; Ris C1 to C8 alkyl; Si is silicon; S is sulfur; and Z is Ror of formula II where Ris alkyl, aryl, alkylaryl or arylalkyl;

A tire is provided having a component comprised of a rubber composition containing at least one conjugated diene-based elastomer and a combination of rubber reinforcing fillers composed of rubber reinforcing carbon black, precipitated silica and granular functionalized mineral comprised of at least one of aluminum hydrate (ALOOH) and titanium dioxide. The granular mineral is functionalized by pretreatment with a coupling agent. The granular mineral fillers are pretreated with a coupling agent to promote a combination of rubber reinforcing effect for the mineral fillers and to promote a hydrophobation of the mineral fillers to promote their dispersability in the rubber composition.
