Abstract
Processes for making copolymers comprising treating a reaction mixture of a monomer and a substrate comprising ferromagnetic material located in a polymeric matrix so as to polymerize the monomer in a manner that it forms a polymeric shell grafted on to and surrounding the substrate, the polymerization of the monomer being initiated by adding the components of a redox system sequentially to the reaction mixture.
