Description/Abstract Unsaturated hydrocarbons react with sulfur dioxide in the presence of a peroxide-containing catalyst to form the heaviest molecule polysulfones.^In the light of earlier work on polysulfones, the present authors assert that peroxide-containing ethyl benzene possesses a catalytic effectiveness far superior to that of previously known catalysts for the same conversion.^This catalyst makes possible the yielding of sulfones not only from concentrated olefins, but also from technical gases or fluid hydrocarbon mixes which contain only a small percentage of olefins.^The new catalyst also assists in producing the polyethylene sulfone from either pure ethylene or raw ethylene derived from coking gas.^The process of the new catalyst facilitates the production of polysulfones even from hydrocarbons in the boiling range of gasoline; peroxide-containing ethyl benzene is here far more effective than the earlier catalysts, since peroxide-containing ether is generally not used in this reaction, and since the use of paraldehyde and hydrogen peroxide yields sulfones from the hydrocarbon Kogasin, for example, only in small amounts.^Toluene admits similar treatment.^The polysulfones produced from ethylene, propylene, and butylene are white amorphous substances of extremely low solubility.^Their characteristics correspond fully to those of polysulfones obtained by earlier tests.^The authors describe the separate tests for their work in detail.
