Abstract
AbstractStarting from a commercial sulphonate cation‐exchange resin via sulphonyl chloride and sulphonamide resins, a macromolecular dichloroamine with ca. 6 mmol of active chlorine per gram of resin was prepared. The conditions for its optimum preparation starting from poly(styrene‐co‐divinylbenzene)sulphonamide (poly(St‐Co‐DVB)SO2NH2) were stated. The possibility of iterated chlorination and dechlorination of the product was proved. Its stability in the range of 20–100°C, both in the dry state and in aqueous media, was determined. Moreover, its derivatographic examinations up to 1000°C were performed. Examples for the use of the macromolecular dichloroamine as a polymer supported reagent for chlorination, oxidation of several organic and inorganic species and water disinfection are given.
