Abstract

A procedure for the aqueous suspension polymerization of ethylenically unsaturated monomers in the presence of a catalyst system containing at least one organic peroxydicarbonate used at a rate of 0.01 to 3 parts of catalyst per 100 parts of monomer and prepared immediately before polymerization by reaction of a haloformate with an inorganic peroxide in the presence of water, a solvent not miscible with water and possibly a base, a procedure characterized by the fact that peroxydicarbonate is prepared in the presence of a quantity of solvent between 100 and 0.20 and preferably between 10 and 1 parts by weight of solvent for each part of haloformate, of an amount of water between 10 and 1000 and preferably between 25 and 100 parts by weight of water for each part of haloformate, due to the fact that the whole of the reaction medium in which it has been placed is introduced into the polymerization autoclave prepared the peroxydicarbonate, and by the fact that the suspension polymerization is carried out in a manner known per se.
