Patent ID: 8211975

Claim:
A fuser member comprising a substrate, and thereover, an outer layer comprising a fluorinated polyimide comprising the following Formula I wherein Ar independently represents a fluorinated hydrocarbon group, Rf 2 and Rf 3 are independently selected from the group consisting of -R 1 - and -R 1 -D-R 2 -, wherein R 1 and R 2 each comprises a fluorinated hydrocarbon group, and D represents a divalent linkage group, L represents a linkage group, l and m each individually represent a mole fraction of repeating units, wherein the value ranges from about 0.1 to about 0.99, p represents an integer ranging from about 20 to about 1,000, Q is an end group, and o is 0 or 1, wherein R 1 is an aliphatic group selected from (a) CH 2 —(CF 2 ) x —CH 2 , —(C n F 2n O) x —, —CH 2 CF 2 O(C n F 2n O) x CF 2 CH 2 —, —CH 2 CH 2 OCH 2 CF 2 O(C n F 2n O) x CF 2 CH 2 OCH 2 CH 2 —, and mixtures thereof, wherein n is a number of from about 1 to about 6, and x is a number of repeating units of from about 1 to about 500; and (b) and mixtures thereof, wherein i, j, and k each represent a number ranging from 0 to about 200, and wherein the total of i+j+k is a number ranging from about 0.3 to about 500.
