Reactions caused by corona discharges (passing through atmospheres of methane, hydrogen or argon) striking the surfaces of aqueous solutions containing long chain fatty acid salts resulted in the formation of solid and insoluble products. These results show that the fatty acid ions were oriented on the aqueous surfaces in such a way that the hydrocarbon chains projected out of the surfaces. Surface layers of long chain alcohols reacted similarly but short and branched chain compounds were not polymerized under the experimental conditions that were used. When methane or hydrogen was used as the discharge gas, reactions occurred along the hydrocarbon chains of the compounds so that the products consisted of networks of many short hydrocarbon chains. These reactions were probably caused by the penetration of hydrogen atoms into the surface layers. Joining of terminal methyl groups of the hydrocarbon chains was the main reaction observed when argon was used as the discharge gas.
