Abstract

See full text

The present invention relates to a method for preparing an aqueous dispersion of water-soluble polymers, which comprises a step (E) of radical polymerization, wherein the following are brought into contact in an aqueous medium (M) in which the synthesised polymer is not soluble:

    at least one ethylenically unsaturated monomer which is soluble in the aqueous medium (M);at least one source of free radicals; anda reactive stabiliser which comprises: a polymer chain (CP) which is soluble in the medium (M),a group (G) providing the radical polymerization of step (E) with a living and controlled nature, such as, for example, a group carrying a thiocarbonylthio —S(C═S)— group.
