Abstract

The invention relates to copolymers containing 0.01 to 35 mole-% relative to the total monomer composition, of one or more polymerized perfluoroalkyl group-containing monomer units, 55 to 99.99 mole-% of one or more polymerized N-vinylamide monomer units, and 0 to 10 mole-% of one or more further comonomers, a process for the preparation of the copolymers, and their use as emulsifiers and dispersants in aqueous systems.
