Abstract
The present invention relates to stable aqueous dispersions comprising one or a number of hydroxylated fluorinated copolymers consisting of vinylidene fluoride and/or of trifluoroethylene, of tetrafluoroethylene, of one or a number of hydroxylated allylic monomers, and optionally of one or a number of monomers chosen from non-hydroxylated vinyl ethers. The stable aqueous dispersions optionally further comprise one or a number of acrylic copolymers consisting of methyl methacrylate and of one or a number of other alkyl (meth)acrylate(s), which are optionally functionalized or substituted. The stable aqueous dispersions are prepared by dispersion in water of an organic solution of the above copolymers and then by removal of the organic solvent. They can in particular be used as binders for aqueous-phase paints or varnishes.
