Patent ID: 7887926

Claim:
A polymer comprising at least three blocks, the first block comprising poly(styrene), the second block comprising poly(ethylene-random-butylene), and a third block comprising functionalized poly(isoprene); wherein repeating units of the functionalized poly(isoprene) block comprise hydroxyl groups and one or more ether linked side chains comprising R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , or a combination thereof; wherein R 1 is —(OCH 2 CH 2 ) n OCH 3 wherein each n is independently 8-16; R 2 is —O(CH 2 ) x (CF 2 ) y F wherein each x and y are independently 2-12; R 3 is —(OCH 2 CH 2 ) q (CF 2 CF 2 ) r F wherein each q is independently 1 to about 25 and each r is independently 0 to about 18; R 4 is —(OCH 2 OCH 2 ) n OC 6 H 4 (CH 2 ) n CH 3 wherein each n is independently 6-16; R 5 is —(OCH 2 OCH 2 ) n (CH 2 ) n CH 3 wherein each n is independently 8-16; R 6 is —(OCH 2 OCH 2 ) n (CH 2 ) 3 Si(CH 3 )(OSi(CH 3 ) 3 ) 2 wherein each n is independently 8-16.
