    Abstract: A farnesene polymer is provided having a glass transition temperature greater than zero degrees Celsius that is obtained by combining a farnesene monomer and a solvent and optionally adding one or more vinyl aromatic comonomers to provide a monomer feed and polymerizing the monomer feed with a Friedel-Crafts catalyst. The farnesene polymer may be included as a resin in a rubber composition for tire applications.

    Abstract: According to an aspect of the invention, a curable rubber composition is provided which includes a high molecular weight diene elastomer; optionally, a carbon black composition; a silica composition; and a farnesene polymer comprising farnesene monomers. The farnesene polymer is modified with at least one silane group, has a number average molecular weight of 1,000 g/mol to 100,000 g/mol, and has a glass transition temperature of equal to or less than −50° C. According to another aspect of the invention, a method for producing a rubber composition for use in a tire is provided. The method includes forming a composition by mixing a farnesene polymer modified with at least one silane group, a silica composition, a high molecular weight diene elastomer, and optionally a carbon black composition, the farnesene polymer comprising farnesene monomers; and curing the composition.

    Abstract: A modified polymer includes a diene-based polymeric chain and at least one end terminated with a blocked isocyanate group. The blocked isocyanate group may be the reaction product of an isocyanate and a blocking agent, and the blocking agent is selected, such that the modified polymer deblocks at temperatures of at least 100 C. An aqueous emulsion of the modified polymer may be provided that may be surfactant-free. The emulsion may be combined with one or more latexes to provide a treatment solution for a fabric or fiber that does not require the use of resorcinol and formaldehyde. Once treated and dried, the fabric or fiber may be used to impart tensile strength to rubber products, such as tires, air springs, flexible couplings, power transmission belts, conveyor belts, and fluid routing hoses.
