Abstract

One or more ethylenically unsaturated monomers are polymerized, e.g. in bulk, solution, or aqueous emulsion or suspension, in the presence of a silver alkyl initiator and in the absence of oxygen. The silver alkyl, e.g. silver ethyl, is preferably prepared in situ, e.g. by reacting lead tetra-alkyl with silver nitrate in the presence of a solvent for the reactants such as methanol. Monomers mentioned are vinyl chloride, vinyl acetate, ethylene, propylene, acrylonitrile, and methyl methacrylate, and mixtures of ethylene, propylene or vinyl acetate with vinyl chloride. In aqueous emulsion the emulsifying agent may be polyethylene glycol mono-oleate, the disodium salt of methylene di-naphthalene sulphonic acid, whilst in aqueous suspension, the suspending agent may be polyvinyl alcohol. Specified solvents for solution polymerization are xylene, cyclohexanone, and acetone. The polymerization may be effected at temperatures as low as - 40 DEG C.
