Abstract

Abstract Translated from German Verfahren zur Herstellung von organischen Polysäuren aus monomeren monofunktionellen Säuren, wie (Meth)acrylsäure, Monomeren ohne Säurefunktion und gegebenenfalls Dicarbonsäuren bzw. deren Anhydriden durch radikalische Substanzcopolymerisation in kontinuierlicher Fahrweise unter erhöhtem Druck bei 200 bis 400 °C und gegebenenfalls Neutralisation der erhaltenen Polysäuren, weiterhin die Polysäuren, die nach diesem Verfahren hergestellt worden sind, und ihre Verwendung als Phosphatersatzstoffe und Inkrustierungsinhibitoren in Wasch-und Reinigungsmitteln. Process for the preparation of organic polyacids from monomeric monofunctional acids, such as (meth) acrylic acid, monomers without acid function and, if appropriate, dicarboxylic acids or their anhydrides by free-radical substance copolymerization in a continuous procedure under elevated pressure at 200 to 400 ° C. and optionally neutralization of the polyacids obtained the polyacids which have been prepared by this process and their use as phosphate substitutes and incrustation inhibitors in detergents and cleaning agents.
