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:
C4F9—X—OH
- wherein:
-
- R=hydrogen or an alkyl group of 1 to 4 carbon atoms,
- m=2 to 8,
- Rf=CnF2+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.
