The invention concerns a method for polymerisation in aqueous suspension of vinyl chloride alone or mixed with another vinyl monomer, wherein the initiator comprises at least a compound selected among dialkyl peroxydicarbonates, peroxy-tert-alkanoates and diacyl peroxydes, and it consists in using, as short stopper of polymerisation, a stable nitroxyl radical. The resulting resins have good whiteness. |
