Abstract
Process for polymerizing in a reactor containing a polymerization mixture, and in aqueous suspension, a halogen-containing vinyl monomer, using a lipo-soluble initiator which generates free radicals, in the presence of an effective amount of an inhibitor of crust formation derived from a sulfur-containing organic compound, wherein the inhibitor of crust formation consists of anions derived from at least one arylsulfonic acid.
