    Abstract: The invention relates to a process for the preparation of an organic solution of dialkyl peroxydicarbonate which is particularly suited for use in the aqueous suspension polymerization of halogenated monomers. According to this process, the dialkyl peroxydicarbonate, prepared by the reaction in water of appropriate amounts of alkyl haloformate with an inorganic peroxide, is separated by extraction by means of a water-insoluble organic solvent chosen from conventional chain-regulating agents for halogenated polymers.
