Abstract

324,004. Johnson, J. Y., and Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Aug. 14, 1928. Caoutchouc, synthetic.-The polymerization of diolefines is effected with the addition of a diluent non-reactive, hydrocarbon. The polymerization is effected by means of sodium, or according to the first Provisional Specification it may be effected by heat, or the diolefine may be emulsified with an aqueous liquid and polymerized in presence of proteins by means of enzymes or oxidizing agents such as hydrogen peroxide. The diluent hydrocarbon may have a boiling-point similar to the diolefine or below or above it, and may even be of high boiling-point up to about 250‹ C. though these last would usually be employed in small quantities. The boiling-point of the diluent is advantageously so low that it can be removed after the polymerization by distillation with or without a vacuum at moderate temperature. In the examples butadiene is mixed with cyclohexane, petroleum, ether, benzene, butylene and amylene respectively, and polymerized by sodium. Specifications 9722/11, 17235/12, 283,841, and 298,584 are referred to.
