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.
