Patent ID: 8314196

Claim:
A hydrogenated polyfarnesene prepared by: (a) polymerizing a farnesene in the presence of a catalyst to form a polyfarnesene; and (b) hydrogenating at least a portion of double bonds in the polyfarnesene in the presence of a hydrogenation reagent to form the hydrogenated polyfarnesene, wherein the polyfarnesene prepared by step (a) 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′ 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 from about 5 wt. % to about 99 wt. %, based on a total weight of the polyfarnesene.
