Abstract

In polymerizing olefinic compounds in aqueous emulsion, the reaction mixture comprises not more than 0.5 per cent of a C2 to C6 amine containing only one nitrogen atom. The invention is applicable to the polymerization of one or more dienes, e.g. butadiene, isoprene, piperylene, dimethyl butadiene, chloroprene, cyanoprene, phenyl butadiene and methyl pentadiene; of acrylo- and methacrylonitriles, methyl acrylate and methacrylate, ethyl fumarate, methyl vinyl ketone and methyl isopropenyl ketone; and of their mixtures with dienes. Amines specified are ethyl, propyl, butyl, amyl and hexyl amines; diethyl and dipropyl amines; trimethyl, dimethyl ethyl and triethyl amines; piperidine, morpholine, pyrrolidine, piperazine; tetraethyl ammonium hydroxide; mono-, di- and triethanolamines; dimethyl and diethyl amino ethanol and their methyl and ethyl ethers; chloromethyl and chlorobutyl amines. Suitable emulsifying agents are alkali metal and ammonium salts of oleic, stearic and palmitic acids and fatty acid mixtures obtained by hydrogenation of tallow acids, the sodium salts of isobutylnaphthalene and tetraisobutenyl sulphonic acids, sodium dodecyl sulphate, and dodecylamine hydrochloride or acetate. The catalyst may be hydrogen peroxide with or without metal activators, and its addition compounds, benzoyl peroxide, tert.-butyl hydroperoxide, perborates, persulphates and iron carbonyl. Modifiers, e.g. heptyl, octyl, diisobutyl, dodecyl and "Lorol" (R.T.M.) mercaptans, addition products of primary, secondary or tertiary mercaptans with acrylo- and methacrylonitriles, vinyl ethers and vinyl ketones, and diisopropyl xanthogen disulphide may be present.
