Chlorosulfonated polysulfones and derivatives thereof |
| abstract |
ABSTRACT A polysulfone sulfonyl chloride having recurring units of the formula: Sulfonamides quaternized products and other derivatives of the above polysulfone. These derivatives are suitable for the formation of membranes, coatings, ion exchange resins, ion exchange fibers selectively permeable barrier films, and the like. The preparation of these compounds is also disclosed. It includes the chlorination of hydroxysulfonyl sites of sulfonated polysulfones, and optionally further reaching the chlorosulfonyl polysulfone polymer via the chlorosulfonyl polymer. |
