Abstract
Terpolymers of N-alkyl perfluoroalkanesulfonamidoalkyl (meth)acrylate, higher alkyl (meth)acrylate and polyoxyalkylene glycol mono- to bis-(meth)acrylates in a prescribed range of concentrations provide useful solubilities in organic solvents including aliphatic, cycloaliphatic and aromatic hydrocarbons with minimal formation of foams. Textiles and surfaces coated with the terpolymers show desirable oleophobicity.
