Patent ID: 8592543

Claim:
A polyfarnesene derived from a farnesene and a vinyl monomer, wherein the polyfarnesene comprises one or more polymer molecules, each of the molecules independently having formula (X′): wherein each of n and m is independently an integer from 1 to about 100,000; X is derived from the farnesene and has one or more of formulae (I′)-(VIII′): and Y is derived from the vinyl monomer and has formula (IX′): wherein R 1 has formula (XI): R 2 has formula (XII): R 3 has formula (XIII): and R 4 has formula (XIV): wherein R 5 is carboxy, alkoxycarbonyl, hydroxyalkoxycarbonyl, aminoalkoxycarbonyl, pyridyl, cyano, halo or acyloxy; R 7 is H, alkyl or halo; and each of R 6 and R 8 is independently H, wherein the farnesene is α-farnesene or β-farnesene or a combination thereof, wherein an amount of the farnesene is at least 25 mole %, based on the total amount of the polyfarnesene.
