Abstract
A composition comprises a copolymer comprising repeating units derived from at least one co-reactant comprising two or more acrylate groups and repeating units derived from a fluoroacrylate comprising the reaction product of: (a) at least one fluorochemical alcohol represented by the formula: C.sub.4F.sub.9--X--OH wherein: ##STR00001## R=hydrogen or an alkyl group of 1 to 4 carbon atoms, m=2 to 8, R.sub.f.dbd.C.sub.nF.sub.2n+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; wherein the composition is coatable.
