ABSTRACT OF THE DISCLOSURE A process for the manufacture of aqueous solutions of anti-scaling agents, starting from maleic anhydride and vinyl acetate (and optionally from a third monomer), characterized in that: (A) the amount of vinyl acetate ranges from 40 to 70% by moles, with respect to the sum of all the comonomers, the amount of maleic anhydride ranges from 30 to 50% by moles, with respect to said sum, and the amount of termonomer ranges from 0 to 30% by moles, with respect to said sum, the molar ratio vinyl acetate/maleic anhydride being equal to or higher than 1; (B) maleic anhydride, vinyl acetate (and optionally said third monomer) are co-polymerized in an organic diluent having medium or low polarity; (C) the anhydrous suspension, obtained according to (B), is directly subjected to a reactive extraction with water.
