Abstract
Abstract Polymeric alcohol derivatives consisting of polymeric alcohol sulfonic acids containing S-xanthogenate ester substituents of the general formula AND SALTS OF SAID POLYMERIC ALCOHOL SULFONIC ACIDS PREPARED BY REACTION OF A SULTONE, E.G., 1,3-PROPANE SULTONE, WITH THE FREE ACID FORM OR A SALT OF A POLYMERIC ALCOHOL XANTHOGENATE ESTER, E.G., CELLULOSE XANTHATE. The novel omegasulfonated polymeric alcohol derivatives have physical and chemical properties, e.g., solubility, viscosity, reactivity with cross-linking agents, and an anionic character, adapting them for advantageous use in a wide range of applications. The derivatives find particular utility as antistatic and antisoiling agents which are effective when applied to a wide range of soil receptive substrates, e.g., natural and synthetic textiles.
