The present invention is directed to a benzoxazine-functionalized diene-based elastomer comprising polymer chains including repeat units which include conjugated diolefin monomers, such as 1,3-butadiene and isoprene. Additionally, said elastomer comprises at least one benzoxazine connected to a polymer chain via a spacer, wherein the spacer has a length ranging from 3 to 8 atoms. A further aspect of the present invention is directed to a rubber composition comprising such an elastomer, an article of manufacture comprising this rubber composition, and a method of making said benzoxazine-functionalized diene-based elastomer.

Diene-based elastomer and a rubber composition

The present invention is directed to a rubber composition comprising an elastomer, a filler, and a block-copolymer. According to the invention, the block-copolymer comprises (i) an elastomer block and (ii) a thermoplastic block comprising a poly alkylacrylate, wherein the alkylacrylate comprises a polycyclic substituent at its single bonded oxygen atom. Moreover, the present invention is directed to a block-copolymer.

Rubber composition comprising a block-copolymer

In a first aspect of the present invention, a rubber composition is provided, comprising at least one rubber, at least one filler, at least one thermoplastic polymer, wherein the thermoplastic polymer is a poly alkylacrylate, and wherein the alkylacrylate comprises a polycyclic substituent at its single bonded oxygen atom. In another aspect of the invention, an article of manufacture such as a tire, a power transmission belt, a hose, a track, an air sleeve, and a conveyor belt is provided which comprises the rubber composition in accordance with the first aspect.

Rubber composition and an article of manufacture comprising a rubber composition

The invention is directed to a pneumatic tire comprising a vulcanization rubber composition, the vulcanizable rubber composition comprising: from 30 to 90 phr of a first functionalized styrene-butadiene rubber having a glass transition temperature Tg1 ranging from −70 to −50° C.; from 10 to 50 phr of a second functionalized styrene-butadiene rubber having a glass transition temperature Tg2 ranging from −110 to −70° C.; wherein Tg2−Tg1 is at least 10° C.; from 0 to 40 phr of at least one additional elastomer; from 50 to 150 phr of silica; from 0 to 50 phr of a hydrocarbon resin; and from 10 to 50 phr of an oil.

Pneumatic tire

The present invention is directed to a rubber composition comprising 100 phr of one or more diene-based elastomers, 30 phr to 200 phr of a filler, and a benzoxazine which is the reaction of (i) a diphenol comprising two phenol groups and a bridge covalently connecting the two phenol groups, (ii) an aldehyde derivative, and (iii) an amine, wherein the bridge is connected to at least one of the phenol groups at a meta position of said at least one phenol group. The present invention is also directed to a rubber product comprising such a rubber composition and the use of such rubber products in tire components.

Rubber composition and a rubber product

The present invention is directed to a rubber composition comprising 100 phr of at least one diene-based rubber, 30 phr to 250 phr of at least one filler, and 1 phr to 40 phr of an epoxidized and aminated fatty acid ester, wherein the epoxidized and aminated fatty acid ester is obtained from the reaction of an epoxidized fatty acid ester with an aliphatic amine. Furthermore, the present invention is directed to a rubber product, such as a tire, comprising such a rubber composition.

The present invention is directed to a pneumatic tire having a tread comprising a vulcanizable rubber composition comprising, based on 100 parts by weight of elastomer (phr),

The present invention is directed to a copolymer of styrene and &#x3b1;-methylstyrene comprising an alternating sequence of styrene and &#x3b1;-methylstyrene residues, and a method to make the copolymer.

Anionic polymerization of alpha-methylstyrene/styrene alternating copolymer

The invention is directed to a pneumatic tire having a rubber tread of a cap/base construction comprising an outer rubber tread cap layer containing an outer running surface and an underlying rubber tread base layer; wherein said tread cap layer comprises at least two circumferential, longitudinal rubber tread cap zones; wherein said tread cap zones individually extend from said tread cap running surface radially inward to said tread base layer; wherein said at least two tread cap zones comprises a first tread cap zone and a second tread cap zone adjacent to the first tread cap zone; the first tread cap zone and the second tread cap zone each independently comprising a vulcanizable rubber composition.

Pneumatic tire having first tread cap zone and second tread cap zone

The invention relates to the preparation of a rubber composition containing a pre-treated precipitated silica and a tire having a component comprised of such rubber composition. The pre-treated silica is a precipitated silica having been pre-treated with a silica coupling agent comprised of an alkoxyorganomercaptosilane to form a precipitated silica/coupling agent composite prior to its blending with a rubber composition. The rubber composition preparation involves reacting said pretreated silica/coupling agent composite with a combination of bis(3-triethoxysilylpropyl) polysulfides in situ within the rubber composition.

Preparation of silica reinforced rubber composition and tire with component thereof

The invention relates to a pneumatic tire having a cap/base configuration comprised of an outer tread cap rubber layer, with a tread running surface, and an underlying tread base rubber layer, where the base rubber layer contains syndiotactic polybutadiene with a diverse blend of carbon blacks.

Tire tread base containing syndiotactic-1,2-polybutadiene with diverse carbon blacks

The invention is directed to a pneumatic tire having a tread comprising a vulcanizable rubber composition comprising, expressed as parts by weight per 100 parts by weight of elastomer (phr),

The invention relates to a tire having a lug and groove configured rubber tread having an outer rubber cap layer with a running surface and an underlying specialized transition rubber layer. The transition rubber layer is specialized in a sense of containing at least one of partially depolymerized rubber, particulate pre-cured rubber and coal dust. The outer tread cap layer is comprised of ground-contacting tread lugs with the tread running surface and associated tread grooves positioned between said tread lugs. The tread grooves may extend radially inward through the outer tread cap layer and, optionally, into the transition tread layer. The rubber tread configuration may also optionally also include a tread base rubber layer underlying the transition rubber layer.
