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:in-line-formulae description="In-line Formulae" end="lead"?C4F9—X—OHin-line-formulae description="In-line Formulae" end="tail"?wherein:R=hydrogen or an alkyl group of 1 to 4 carbon atoms,m=2 to 8,Rf═CnF2n+1,n=1 to 5,y=0 to 6, andq=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.
