Abstract
Process for obtaining copolymers of acrylonitrile, characterized in that acrylonitrile is polymerized in solution or in aqueous emulsion, with free radical catalysts with unsaturated cyclic sulfones, which conform to the general formula ** (See formula) ** wherein R and R 'are hydrogen atoms or hydrocarbon radicals, especially alkyl and aryl radicals, the proportion of cyclic sulfones comprised in the acrylonitrile copolymer being from 0.1 to 20%.
