Abstract (en)
[origin: CA3118202A1] The present invention concerns a method for preparing a polymer by inverse emulsion polymerisation comprising the following steps: a) Preparing an aqueous phase comprising at least one water-soluble monomer and at least one water-soluble precursor of formula (I): formula (I) b) Preparing an organic phase comprising a lipophilic solvent and at least one water-in-oil surfactant, c) Mixing the aqueous phase and the organic phase by stirring in order to form an inverse emulsion, d) Once the inverse emulsion is formed, adding a radical polymerisation initiator to the inverse emulsion, and obtaining a polymer by polymerisation of the at least one water-soluble monomer.
