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

A method including reducing a particle size of lignin particles to an average particle size less than 40 nanometers; after reducing the particle size, combining the lignin particles with a polymeric material; and forming a structure of the combination. A method including exposing lignin to a diazonium precursor including a functional group; modifying the lignin by introducing the functional group to the lignin; and combining the modified lignin with a polymeric material to form a composite. An apparatus including a composite of a polymer and lignin wherein the lignin has an average particle size less than 100 micrometers.

Lignin nanoparticle synthesis

The invention relates to functionalized lignin, rubber compositions which contain functionalized lignin and to products which have at least one component comprised of such rubber composition.

Functionalized lignin, rubber containing functionalized lignin and products containing such rubber composition

The present invention is directed to a camouflage tire suitable for use in various vehicle use environments wherein it is desirable to reduce or eliminate a viewer's visual perception of the tire against the given environmental background.

Camouflage tire

This invention relates to a precipitated silica reinforced conjugated diene-based elastomer composition containing an alkoxysilane coupled, in-chain functionalized, conjugated diene-based elastomer and to a tire having at least one component thereof. Said in-chain functionalized conjugated diene-based elastomer is a conjugated diene-based elastomer which contains a plurality of at least one of in-chain p- and m-(2-pyrrolidinoethyl) styrene (PES) and m-(2-pyrrolidino-1-methylethyl) alpha-methylstyrene (PAMS) groups.

Rubber composition containing an alkoxysilane coupled in-chain functionalized elastomer and tire with component thereof

The present invention discloses a process for devulcanizing cured rubber into devulcanized rubber that is capable of being recompounded and recured into useful rubber products, said process comprising heating the cured rubber to a temperature which is within the range of about 150&#xb0; C. to about 300&#xb0; C. under a pressure of at least about 3.4&#xd7;10Pascals in the presence of a mixture of carbon dioxide and 2-butanol.

Devulcanization of cured rubber

A method of treating a metallic cord to improve its ability to adhere to rubber is disclosed. The method involves contacting the metallic cord with a naphthenic oil containing from 1 to 53 percent by weight of a soluble cobalt salt and thereby deposit from 0.002 to 0.7 grams of cobalt per kilogram of steel to the metallic cord.

Method of treating metallic cord

Camouflage tire sidewall

This invention relates to rubber composition which contains a thermoplastic polymer and use thereof as a tire sidewall component and/or tread supporting ring for use in a tire/rim assembly. Such tire sidewall component may be a sidewall insert and/or apex of a rubber composition which contains a thermoplastic polymer.

Rubber composition containing a thermoplastic polymer and tire sidewall component or tire support ring comprised of such rubber composition

This invention discloses a process for devulcanizing the surface of reclaimed rubber crumb into surface devulcanized reclaimed rubber crumb that is suitable for being recompounded and recurred into high performance rubber products, said process comprising the steps of (1) heating the reclaimed rubber crumb to a temperature within the range of about 150&deg; C. to about 300&deg; C. under pressure of at least about 3.4&times;10 Pascals in the presence of 2-butanol to devulcanized the surface of the rubber crumb thereby producing a slurry of the surface devulcanized reclaimed rubber crumb in the 2-butanol, wherein the reclaimed rubber crumb has a particles size which is within the range of about 325 mesh to about 20 mesh, and (2) separating the surface devulcanized reclaimed rubber crumb from 2-butanol.

Surface devulcanization of cured rubber crumb

This invention discloses a process for devulcanizing the surface of reclaimed rubber crumb into surface devulcanized reclaimed rubber crumb that is suitable for being recompounded and recured into high performance rubber products, said process comprising the steps of (1) heating the reclaimed rubber crumb to a temperature which is within the range of about 150&deg; C. to about 300&deg; C. under a pressure of at least about 3.4&times;10 Pascals in the presence of a solvent selected from the group consisting of alcohols and ketones, wherein said solvent has a critical temperature, which is within the range of about 200&deg; C. to about 350&deg; C., to devulcanize the surface of the rubber crumb thereby producing a slurry of the surface devulcanized reclaimed rubber crumb in the solvent, wherein the reclaimed rubber crumb has a particle size which is within the range of about 325 mesh to about 20 mesh, and (2) separating the surface devulcanized reclaimed rubber crumb from the solvent.
