| abstract | Monomeric material containing a CH2 = C < group is polymerized in aqueous emulsion in a polyamine organic peroxide anti-freeze system at -15 to -40 DEG C., in the presence of (1) not more than 0.8 millimols. per 100 parts monomers of a water-soluble salt of iron, cobalt, manganese, vanadium or copper and (2) 2, 21-dipyridyl ethylenediamine tetraacetic acid or an alkali metal or ammonium salt of ethylene diamine tetraacetic acid, the ratio in mols. of the metal salt to the tetraacetic compound being 1:1 to 1:5. Specified monomers are butadiene, 2, 3-dimethyl-1:3-butadiene, isoprene, piperylene, 3-furyl-1:3-butadiene, 3-methoxy-1:3-butadiene, chloroprene, bromoprene, methylchloroprene, styrene, alkyl styrenes, 1-chlorostyrene, vinyl naphthalene, acrylic acid, methacrylic acid, methylacrylate, methyl a -chloro-acrylate, methyl methacrylate, acrylonitrile, methacrylonitrile, methacrylamide, p-methoxystyrene, alpha-methylstyrene, methyl isopropenyl ketone, methyl vinyl ketone, methyl vinylether, vinylethinyl alkyl carbinols, vinyl acetate, vinyl chloride, vinylidene chloride, vinylfurane, vinylcarbazole, vinylacetylene, and others. It is preferred to use butadiene-1:3 with styrene, alpha-methylstyrene, vinyltoluene or chlorstyrene. Specified salts are iron sulphate and iron nitrate. It is preferred that the polyamine is a polyalkylene polyamine such as tetraethylene pentamine and that the peroxide is cumene peroxide. |
