Abstract
In a first stage, a heterocyclic oxygen compound is polymerized by an ionic route in a vinyl halide and, in a second stage, the vinyl halide, to which other unsaturated monomers capable of being polymerized by a radical route may be added if desired, is polymerized by a radical route in aqueous dispersion and in the presence of the polymerization mixture originating from the first stage.
