A vulcanizate prepared by a method comprising introducing an elastomer, a filler, and a polar polysulfide crosslinking agent to form a masterbatch and introducing a curative to the masterbatch to form a vulcanizable composition. Vulcanizing the composition to graft the polar group from the crosslinking agent onto an elastomer to increase the hydrophilicity of the composition.

Rubber compositions prepared with a polar polysulfide crosslinking agent

A vulcanizable rubber composition comprising (i) a rubber component including a polyisoprene elastomer, (ii) a sulfur-based curative, (iii) zinc oxide, and (iv) a eutectic composition.

Rubber compositions for pneumatic tires

A method for preparing a functionalized polymer includes the steps of (i) polymerizing monomer to form a reactive polymer; and (ii) reacting the reactive polymer with a [poly(hydrocarbylene glycol) hydrocarbyl ether] (meth)acrylate.

Functionalized polymers having thermoresponsive behavior

A method for forming a polymer-filler composite having advantageous bound filler content, the method comprising (a) providing a guayule cement; (b) introducing particulate filler to the guayule cement to form a solution masterbatch; and (c) desolventizing the solution masterbatch to form a polymer-filler composite.

Polymer-filler composites with guayule rubber

A method of preparing a sidewall support, the method comprising the steps of (i) providing a vulcanizable composition including an elastomer, a filler, a curative, and a eutectic composition; (ii) fabricating the vulcanizable composition into a green sidewall support; and (iii) subjecting the green sidewall support to curing conditions.

Sidewall supports for pneumatic tires

A process for preparing a rubber vulcanizate, the process comprising (i) providing a vulcanizable composition of matter including a sulfur-based curative, zinc oxide, and a eutectic solvent; and (ii) heating the vulcanizable composition to thereby effect vulcanization.
