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.

Abstract: 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.
