Abstract
Process for the production of copolymers, starting from mixtures of monomers, copolymers containing approximately 0.1-5% of unsaturated alpha-beta acids, characterized in that the polymerization is carried out in aqueous phase with a ph value corresponding approximately to the ph value of the unsaturated acid, or is less than the same, in the presence of a non-ionogenic emulsifier or of an ionogenic emulsifier whose acid component has at least the same acidity as the reaction liquid.
