| abstract | 519,730. Synthetic rubber. I.G. FARBENINDUSTRIE AKT.-GES. Sept..28, 1938, No. 28222. Convention date, Sept. 29, 1937. [Class 2(iii)] Synthetic rubber is produced by polymerizing butadiene hydrocarbons alone or together with other polymerizable substances such as styrene or acrylic nitrile in aqueous emulsion in the presence of non-polymerizable aliphatic mercaptans having at least six carbon atoms. In examples butadiene is polymerized in emulsion with (1) styrene, isohexyl mercaptan, sodium oleate and ammonium persulphate ; (2) styrene, octadecyl mercaptan, sodium isobutylnaphthalene sulphonate, potassium persulphate and alkali hydroxide ; (3) octadecyl mercaptan, sodium isobutylnaphthalene sulphonate, potassium persulphate and alkali hydroxide. The Specification as open to inspection under Sect. 91 includes the use of aromatic mercaptans. This subject-matter does not appear in the Specification as accepted. |
