    Abstract: 1,142,187. N - Sulphamoylsulphonamides. FARBENFABRIKEN BAYER A.G. 11 April, 1967 [14 April, 1966; 28 April, 1966], No. 16579/67. Heading C2C. [Also in Division C3] Novel N 1 -substituted N-(sulphamoyl)-sulphonamides of the formula RSO 2 NHSO 2 NR 1 R 2 in which R is alkyl or aryl which may be substituted with one or more groups which are inert under the reaction conditions and R 1 and R 2 are C 1-6 alkyl or together with the adjacent nitrogen atom form a heterocyclic ring may be prepared (a) by reacting an alkyl metal derivative of a sulphonamide of the formula RSO 2 NHM in which M is an alkali metal atom with a sulphamoyl halide of the formula XSO 2 NR 1 R 2 in which X is a halogen atom at 70-150‹ C. in an inert organic anhydrous solvent in the presence of a base or (b) by reacting an alkali metal derivative of a N-substituted sulphamide of the formula R 1 R 2 NSO 2 NHM with a sulphonyl chloride of the formula RSO 2 X at 70-150‹ C. in an inert anhydrous organic solvent in the presence of a base. Suitable bases include alkali metal carbonates and tertiary amines.

    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 aliphatic or cycloaliphatic sulphonamide of the formula wherein M represents Li, Na, K, Rb or Cs, R1 represents an alkyl or cycloalkyl radical and R2 represents an alkyl radical. Specified salts are those of N-methyl, N-isopropyl or N-isobutyl methane sulphonamide, N-methyl n-butane sulphonamide, N - n - propyl ethane sulphonamide, N-methyl cyclohexane sulphonamide and long-chain aliphatic sulphonamides. Suitable solvents are dimethyl formamide and dimethyl sulphoxide. In examples, dimethyl formamide solutions of polyacrylonitrile are produced using potassium N-methyl or N-isobutyl methane sulphonamide or lithium N-isobutyl or N-isopropyl sulphonamide. The catalyst is deactivated with HCl or toluene sulphonic acid.
