Abstract: A solution of an acrylonitrile polymer is produced by polymerizing acrylonitrile in an organic solvent for polyacrylonitrile, at a temperature of from + 10 DEG to - 68 DEG C. in the presence of 0.1 m.mol. to 0.1 mol., per mol of monomer, of an alkali metal salt of an aromatic sulphonamide of the formula wherein M represents Li, Na, K, Rb or Cs, Ar represents an aryl radical and R1 represents a hydrogen atom or an alkyl radical. Specified salts are those of benzene sulphonamide, benzene -N-methyl sulphonamide, p-toluene N-isopropyl or N-methyl sulphonamide and benzene N-hexyl sulphonamide and suitable solvents are dimethyl formamide and dimethyl sulphoxide. In examples solutions of polyacrylonitrile in dimethyl formamide are produced using as catalyst potassium or sodium p-toluene N-methyl sulphonamide. The catalyst is deactivated with HCl or HCO2H.
