Abstract
The temperature of the polymerization medium of vinyl chloride with the involvement of oil-soluble initiators is controlled essentially by direct and modified injection of an effective amount of a strong inorganic inhibitor of radical polymerization or of a precursor advantageously chosen from iodine and nitrogen monoxide, as well as from alkali metal iodides and nitrites, which are the respective precursors of iodine and of nitrogen monoxide.
