Abstract
Process for the aqueous dispersion polymerisation of halogenated vinyl monomers with the use of radical polymerisation initiators in the presence of a build-up inhibitor chosen from bromide or iodide ions introduced in the form of a salt soluble in water and disassociating therein to give bromide or iodide ions. The process applies, for example, to the aqueous suspension polymerisation of vinyl chloride.
