POLYMERISATION IN AQUEOUS SUSPENSION OF VINYL CHLORIDE

摘要

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