Abstract

522,665. Synthetic rubber. CARPMAEL, A. (I. G. Farbenindustrie Akt.-Ges.). Dec. 20, 1938, No. 37049. [Class 2 (iii)] The polymerization of butadiene 1-3 and its substitution products such as isoprene, dimethyl butadiene and 2-chlorbutadiene alone or in conjunction with other polymerizable substances such as styrene and acrylic nitrile is effected in aqueous alkaline emulsion containing watersoluble capillary-active substances which are soluble in both acid and alkaline media, and also water-soluble salts of unsaturated drying-oil acids. The capillary-active substances may be alkylated naphthalene sulphonic acids, fatty acid alcohol sulphonates, higher fatty acids containing a sulphonic acid group, compounds of the formula R.CO.X.R<SP>1</SP> SO 3 H where R is a chain of at least 8 carbon atoms, X is oxygen, NH or N-alkyl, and R<SP>1</SP> is a lower alkyl group such as C 2 H 4 , and products formed by condensing fatty alcohols containing more than 8 carbon atoms such as oleyl alcohol with several molecules of ethylene oxide. The salts of drying-oil acids may be alkali salts of linoleic acid, wood oil acid, or their isomers, or the acids of drying train oil. The capillary-active substances may be used in concentrated solution and are used in quantity gteater than the other emulsifying agents, which latter are precipitated together with the synthetic rubber and have a catalytic effect in the plastifying of the product. In examples there are polymerized in emulsion (1) dimethyl butadiene with isobutylnaphthalene sulphonate, linoleic acid, sodium hydroxide and hydrogen peroxide; (2) butadiene and styrene with the same additions ; (3) butadiene, acrylic nitrile, sodium isobutylnaphthalene sulphonate, sodium hydroxide, drying train-oil acid and hydrogen peroxide ; (4) butadiene and styrene with a condensation product of oleyl alcohol and eight molecules of ethylene oxide together with sodium linoleate and ammonium persulphate ; (5) butadiene and styrene with the sodium salt of α-sulphostearic acid, sodium linoleate, sodium pyrophosphate and ammonium persulphate ; the sodium sulphostearate may be replaced by oleyl taurine. Specification 513,116 is referred to.
