1. A partially fluorinated copolymer comprising the reaction product of monomers copolymerized in the following percentages by weight:
a) from about 45% to about 75% of one or more monomers of Formula (I):
Rf-L-Q-C(O)—CR1═CH2 (I); b) from about 25% to about 30% of one or more monomers of Formula (II):
RH-Q-C(O)—CR2═CH2 (II); c) from about 0.5% to about 15% of one or more monomers of Formula (III):
R—(OCH2CH2)n—(OCH2CH(CH3))pQ-C(O)—CR3═CH2 (III); d) from about 0.1% to about 4% of one or more monomers of Formula (IV): e) from about 0% to about 2% of one or more monomers of Formula (V):
HO—C(O)—CR8═CH2 (V); f) from about from about 0% to about 2% of one or more monomers of Formula (VI):
HO—CH2CH2-Q-C(O)—CR9═CH2 (VI); g) from about from about 0% to about 2% of one or more monomers of Formula (VII):
CH2═CR10C(O)O(CH2CH2O)x(CH2CH(CH3)O)yC(O)CR11═CH2 (VII);wherein
Rf is a linear or branch fluoroalkyl of 2 to 10 carbons optionally interrupted by 1 to 4 interrupting groups —O—, —CH2—, and/or —CHF— groups; RH is a linear, branched, or cyclic alkyl chain of 7 to 22 carbons; each Q is independently —O— or —S—; L is —R12—, —SO2—N(R13)—R15—, —CO—N(R14)—R15—, —CH2CH(OR14)CH2—, —R6—SO2—N(R14)—R15—, or —R15—O—C(O)—N(R14)—R15—; R1, R3, R7, R8, R9, R10, R11 are each independently H or —CH3; R is —H or a linear, branched, or cyclic alkyl chain of 1 to 20 carbons; R2 is —CH3; R4 and R5 are each independently methyl or ethyl; R6, R12 and R15 are each independently a linear or branched divalent alkyl chain of 2 to 10 carbons; R13 and R14 are each independently —H, —CH3, C2 to C10 alkylene, or C1 to C4 acyl; n is 0 to 10 and p is 0 to 10 provided that when p is 0, n is at least 2 and n+p is greater than 0; and x is 0 to 10 and y is 0 to 10 provided that x+y is at least 1; wherein the concentration of monomers of a), b), c), d), e), f), and g) is equal to 100% by weight.
