Patent ID: 8604148

Claim:
A polymer represented by the formula (A): where R 1 is a hydrocarbyl group having greater than 25 carbon atoms; R 2 and R 3 are the same or different and each is hydrogen or a hydrocarbyl group having from 1 to 40 carbon atoms, or R 2 and R 3 are joined to form a five-membered or six-membered ring, or substituted analogs thereof; X is C, N, or 0; n is an integer from 1 to 10,000; and the dotted line indicates an optional double bond; wherein the polymer comprises one or more vinyl terminated macromonomer derived units; wherein R 1 is represented by the formula (B): wherein “C” is one or more derived units of butene, pentene, hexene, heptene, octene, nonene, decene, undecene, dodecene, norbornene, norbornadiene, dicyclopentadiene, cyclopentene, cycloheptene, cyclooctene, cyclooctadiene, cyclododecene, 7-oxanorbornene, 7-oxanorbornadiene, substituted derivatives thereof, and isomers thereof, m is an integer from 2 to 39, and p is an integer greater than or equal to 1.
