<p>A copolymer composition comprising monomers copolymerized in the following percentages by weight: (a) from about 20 % to about 95 % of a monomer, or mixture of monomers, of formula (I): CnF2n+1 (CH2)X [(CF2CF2)y(CH2CH2)z]m- L-C(O)-C(R)=CH2 (I) wherein R is H, Cl, F or CH3; L is O, S, NH, S-(CH2)A S-(CH2)rNH, OC(O)NH-CH2CH2O, NHC(O)NHCH2CH2O, S-(CH2)rOC(O)NHCH2CH2O, or S(CH2)r NHC(O)NHCH2CH2O; subscript n is an integer from 1 to about 6; subscript x is an integer from 1 to about 6; subscripts y, z and m are each independently 1, 2 or 3 or a mixture thereof; and subscript r is from 1 to about 10; and wherein the total number of carbons in the fluorocarbon-hydrocarbon chain segment (formula (I) excluding L-C(O)-C(R)=CH2) ranges from about 8 to about 22, and (b) from about 5 % to about 80 % of at least one of: (i) an alkyl (meth)acrylate monomer having a linear, branched or cyclic alkyl group of from about 6 to about 18 carbons; or (II) a monomer of formula (II) (R2)2N-R3-O-C(O)-C(R)=CH2 (II) wherein R is H, Cl, F or CH3; each R2 is independently a C1 to C4 alkyl; and R3 is a divalent linear or branched C1 to C4 alkylene; and wherein the nitrogen is from about 40% to 100% salinized; or (iii) a mixture thereof.</p> |
