    Abstract: A polymer having a hydrophobic polymer chain derived from monomers of farnesene and other optional monomers, such as dienes and vinyl aromatics. The polymer also includes one or more terminal functional groups, such as an amino group, a glycidyl group, a carboxylic acid group, a (meth)acrylate group, a silane group, an isocyanate group, an acetoacetate group, a phenolic group, and a hydroxyl group. Functional groups, such as carboxylic acids, may also be grafted along the hydrophobic polymer chain. The polymer may be incorporated in curable compositions that optionally include one or more polymer resins having similar functional groups. Methods for preparing the curable polymer compositions are also provided. The curable or cured form of the polymer composition may be used in various products, such as a sealant, a coating, a caulk, an electric potting compound, a membrane, a sponge, a foam, an adhesive, or a propellant binder.

    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 composition is provided for making a polyurethane that may be incorporated in various products, such as a sealant, a coating, a caulk, an electric potting compound, a membrane, a sponge, a foam, an adhesives, and a propellant binder. The composition includes one or more polyols, one or more isocyanate-group containing compounds having an isocyanate group functionality of at least two, and optionally one or more chain extenders. At least one of the polyols is a farnesene-based polyol having a number average molecular weight less than or equal to 100,000 g/mol and a viscosity at 25° C. less than 10,000 cP. The farnesene-based polyol may be a homopolymer or a copolymer of farnesene. The composition may also comprise additional polyols, such as a polyol of a homopolymer or copolymer of a polydiene. Methods of preparing a polyurethane are also provided.
