Abstract

1) Hydrophilic fluoropolymers obtained by radical polymerization, in a precipitating medium, of a mixture of monomers composed of at least one monomer with a perfluoroalkyl side chain, of one or more ionic or ionizable hydrophilic monomer(s) and optionally of one or more nonionic hydrophilic monomer(s).2) Use of these polymers as dispersants or thickeners and as additives in multipurpose fire-fighting emulsifiers.
