Patent ID: 7759444

Claim:
A composition comprising a polyfarnesene, wherein the polyfarnesene has formula (X′): wherein n is from 1 to about 100,000; m is from 0 to about 100,000; X has one or more of formulae (I′)-(VIII′): Y has formula (IX′): wherein R 1 has formula (XI): R 2 has formula (XII): R 3 has formula (XIII): R 4 has formula (XIV): wherein each of R 5 , R 6 , R 7 and R 8 is independently H, alkyl, cycloalkyl, aryl, cycloalkenyl, alkynyl, heterocyclyl, alkoxy, aryloxy, carboxy, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, acyloxy, nitrile or halo, and wherein formula (I′) is in an amount of at most about 80 wt. % and formula (II′) is in an amount of from about 5 wt. % to about 99 wt. %, based on a total weight of the polyfarnesene, with a proviso that when m is 1 or greater, a mole percent ratio of X to Y is from about 1:4 to about 100:1.
