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.

Abstract: A terminal hydroxyl functionalized polyfarnesene is provided. The polyfarnesene has more than two terminal hydroxyl groups per molecule, on average, based on the number average molecular weight. The polyfarnesenes may be homopolymers or copolymers of farnesene. Also provided is a method of making these polyfarnesenes having more than two hydroxyl groups per molecule. A composition for making a polyurethane comprising a diisocyanate and the terminal hydroxyl functionalized polyfarnesene is also provided.

Abstract: Aspects of the present invention relate to polymers, and particularly to farnesene polymers functionalized with one or more oxirane groups and, optionally, one or more hydroxyl groups. According to one aspect of the invention, provided is an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The epoxidized farnesene polymer has at least one of a side chain or a main backbone functionalized with at least one oxirane group and, optionally, at least one terminal end functionalized with a hydroxyl group. In accordance with another aspect of the invention, a method is provided for preparing an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The method includes epoxidizing a farnesene polymer, which may optionally contain one or more terminal hydroxyl groups, to functionalize at least one of a side chain or a main backbone of the farnesene polymer with an oxirane group.

Abstract: A low viscosity polymer having a linear or branched backbone derived from farnesene monomers and at least one terminal-end functionalized with a hydroxyl group. This polymer may be further hydrogenated to reduce unsaturation and acrylated, such that it may be incorporated into a LOCA composition. The LOCA composition may be used in a laminated screen assembly, such as a touch screen, for electronic devices by adhering the LOCA composition between an optically transparent layer, such as a cover glass, and a display. The cured LOCA composition has a refractive index similar to the optically transparent layer. A method of making the low viscosity polymer for the LOCA composition includes anionically polymerizing farnesene monomers, quenching a living end of the polymer to provide the hydroxyl-terminated polymer; hydrogenating the hydroxyl-terminated polymer; and reacting the at least partially saturated hydroxyl-terminated polymer with at least one reagent to provide an acrylate terminated hydrogenated polymer.
