Abstract
Rubber-like products are obtained by polymerizing an aqueous mixture comprising (a) one or more saponifiable derivatives of acrylic acid, methacrylic acid or a -chloracrylic acid; (b) butadiene-1 : 3 or its homologues or mixtures thereof; (c) persulphuric acid or a water-soluble persulphate; and (d) a water-soluble salt of an oxyacid of sulphur having reducing properties. The saponifiable derivatives referred to are the esters, amides and nitriles of the said acids. In examples, butadiene is polymerized with acrylonitrile, methylmethacrylate and ethylacrylate in the presence of sodium hydrosulphite, sodium thiosulphate or sodium sulphite and ammonium persulphate. Phenyl-b -naphthylamine is used as an anti-oxidant and the sodium salts of sulphated sperm oil alcohols are used as emulsifying agent. Disodium hydrogen phosphate and citric acid or sodium acetate and acetic acid are also added. The polymers are coagulated with alcohol and brine and are washed and dried. In another example, 2 : 3-dimethylbutadiene is polymerized with acrylonitrile. Other salts of oxyacids of sulphur mentioned are alkali metal and ammonium pyrosulphites, bisulphites and sulphoxylates and addition compounds with aldehydes and ketones. 2-Methyl butadiene-1 : 3 is specified as a butadiene homologue. Soaps, sulphonated fats and oils and soluble cellulose ethers may be used as emulsifying agents.
