Abstract

312,741. Kleiber, E., and Gilardi, P. March 26, 1928. Rubber substitutes ; resinous compositions.- An elastic mass capable of being vulcanized and used as a rubber substitute is obtained by treating petroleum with nitric acid or with sodium peroxide in the presence of soda lime or sodium acetate or with other oxidizing agent and distilling the neutralized liquid so obtained repeatedly over colophony, heating the distillate with a dilute alkali under pressure causing separation into three layers, and treating one or both of the upper layers with a rubber promoter, e.g. by adding glacial acetic acid and formaldehyde and raw rubber. From a syruplike mass so obtained an elastic mass capable of being vulcanized is obtained by the addition of acetone or alcohol. The residue obtained after the distillation over colophony is a hard resin which may be used as a substitute for copal for varnish.
