Abstract
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:
C4F9—X—OH
wherein:
- Rf=CnF2n+1, n=1 to 5, y=0 to 6, and q=1 to 8; (b) at least one unbranched symmetric diisocyanate; and (c) at least one hydroxy-terminated alkyl (meth)acrylate or 2-fluoroacrylate monomer having 2 to about 30 carbon atoms in its alkylene portion.
