The invention relates to the polymer industry. A reaction mixture of a monomer and a substrate, composed of a ferromagnetic material placed in a polymer matrix, is treated so that a shell of copolymer grafted on and surrounding the substrate is formed. monomer being initiated by the sequential addition to the reaction medium of the components of a redox system. Application of copolymers as ion exchange resins suitable for the purification of aqueous media, such as river water, waste water or industrial waste water. |
