A copolymer comprises repeating units derived from at least one co-reactant comprising two or more mercapto functional groups, and repeating units derived from a fluoroacrylate comprising the reaction product of: (a) at least one fluorochemical alcohol represented by the formula: C4 F9-X-OH wherein: formula (I), R = hydrogen or an alkyl group of 1 to 4 carbon atoms, m = 2 to 8, RfF2n+1, n = 1 to 5, y = 0 to 6, and q = 1 to 8; (b) at least one unbranched symmetric diisocyanate; and at least one hydroxy-terminated alkyl (meth)acrylate or 2-fluoroacrylate monomer having 2 to about 30 carbon atoms in its alkylene portion. |
