POLYOLS DERIVED FROM FARNESENE FOR POLYURETHANES
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.

Farnesene-Based Polymers and Liquid Optically Clear Adhesive Compositions Incorporating the Same
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.

FARNESENE-BASED MACROMONOMERS AND METHODS OF MAKING AND USING THE SAME
A macromonomer precursor is provided that includes a polymeric chain derived from farnesene and a single functional terminal end. The functional terminal end may include a hydroxyl group, an amino group, an epoxy group, an isocyanato group, or a carboxylic acid group. The terminal end of the macromonomer precursor may then be reacted with a (meth)acrylate to form a macromonomer having a (meth)acrylate functionalized terminal end that may be (co)polymerized with radically polymerizable monomers, such as alkyl(meth)acrylate monomers. Alternatively, a copolymer may be obtained by first deriving a poly(meth)acrylate from (meth)acrylate monomers having reactive groups that would allow the macromonomer precursors to be grafted onto the poly(meth)acrylate in a second step. The resulting copolymer may be incorporated as an additive in various formulations, such as a lubricant, a hydraulic fluid, a cosmetic composition, and an adhesive composition.
