Verfahren zur Herstellung von in Chlorkohlenwasserstoffen loeslichen Polyolefinsulfonamiden

摘要

A polyolefine sulphonamide soluble in chlorohydrocarbons is obtained by reacting a sulphochloride of a low pressure polymer of an olefine with 3 to 5 carbon atoms or of a copolymer of two or more olefines with 2 to 5 carbon atoms or a copolymer of such olefines with a diolefine, with ammonia or an amine in a chlorohydrocarbon. The reaction mixture may be diluted with an inert solvent. In the examples: (1) amorphous polypropylene is treated in carbon tetrachloride with chlorine and sulphur dioxide and the sulphochlorinated polymer is then treated with 1,1-diethyl-ethylene-diamine; (2) crystalline polypropylene in o-dichlorobenzene is treated as in (1) and the sulphochlorinated polymer is then treated with monomethylamine or monoethylamine; (3) and (4) sulphochlorinated polypropylene is treated with dimethylamine or liquefied ammonia; (5) and (6) an amorphous ethylene-propylene copolymer or an ethylene-butene-1 copolymer or an ethylene-propylene - dicyclopentadiene terpolymer is treated with sulphur dioxide and chlorine and the sulphochlorinated products then treated with monomethylamine. Piperidine is also mentioned as the amine reactant.
