Popis: A cationic flocculant with an amide-type polymer matrix was synthesized by modifying polyacrylamide according to the Mannich reaction. The use of a modified polymer leads to an increase in the adsorption of the polymer on solid phase particles in an aqueous dispersion of kaolin, an increase in the rate of kaolin sedimentation by a factor of 1.2–1.4, and makes it possible to expand the concentration range of dispersion destabilization compared to polyacrylamide.
