Abstract: 506,427. Hydrocarbon polymers. STANDARD OIL DEVELOPMENT CO. Oct. 26, 1937, No. 29219. Convention date, Dec. 11, 1936. [Class 2 (iii)] Vulcanized rubber-like products are prepared by treating an isobutylene-polymer having a molecular weight below 40,000 with sulphur monochloride or dichloride in an amount of from 1 to 100 per cent of the polymer treated, at a temperature of between 80 and 200‹ C. for a. time between 10 minutes and 50 hours. Fillers and reinforcing agents such as carbon black, litharge, and zinc oxide, and rubber vulcanization accelerators such. as organic amines, e.g. hexamethylene tetramine, or di- or triphenyl guanidine, may be mixed with the polymer before treatment. The treatment may be carried out in the presence of a solvent or diluent such as naphtha; carbon tetrachloride or carbon disulphide. The product may be precipitated from the solvent by alcohol or acetone and may be purified by dissolving in benzene, adding a diatomaceous earth and filtering through powdered sodium hydroxide. The products may be used for the preparation of rubber goods, e.g. tyres, and in the preparation of high-pressure lubricants. In examples, polyisobutylene, either alone or dissolved in 1 : 1 : 2 : 2-tetrachloroethylene or o-dichlorobenzene, is treated with sulphur monochloride. According to the Specification as open to inspection under Sect. 91, the process is applied to a plastic or elastic substantially saturated linear type hydrocarbon material having a molecular weight below 40,000. This subjectmatter does not appear in the Specification as accepted.
