Abstract: The initiation system formed by polyhalogenalkanes, mainly by carbon tetrachloride and O- or N-containing organic compound, was investigated in the case of the emulsion polymerization of vinyl chloride. CCl₄ was found to be the most effective, the effectiveness of CHCl₃ is one fifth of CCl₄; Cl₂CHCHCl₂ and Cl₂C = CCl₂ have virtually no influence on polymerization. From among oxygenous compounds especially alkali cellulose, lignin with sodium hydroxide, alkaline hemicelluloses, paraldehyde, dioxan, ethylene oxide, acetals, and ascorbic acid; from among N-containing compounds morpholine, piperidine, and allylamine are effective. Aqueous solution of an emulsifier is the most suitable, methanol to a lesser degree, and water is the least effective. The mechanism of the formation of initiation system as well as of the initiation of polymerization itself have been discussed.
