Abstract
In order to improve the barrier effect to fats of the cationic fluorinated copolymers of Patent EP 542,598 resulting from the copolymerization of at least one polyfluorinated monomer, of at least one aminoalkyl (meth)acrylate and of at least one vinyl monomer (in particular vinyl acetate), they are subjected to the action of hydrogen peroxide during the salification stage or after the latter.
