Abstract

Procedure for preparing grafted copolymers, characterized by the following successive steps: a polymer is subjected to the action of ozone, this polymer is thus ozonated in the presence of a monomer polymerizable by a radical mechanism, then the ozonides formed on the polymer are decomposed, thus initiating the polymerization of the monomers on the initial polymer.
