Beschreibung
Zusammenfassung:	The present invention relates to high molecular weight non-ionic surfactants comprising terminal anionic end groups or salts thereof, a process for the preparation of such surfactants and the use of such surfactants in decreasing the hardness of aqueous systems, desalination or softening of water, removal of heavy metals from aqueous systems contaminated with such metals, and in industrial and domestic wash processes and products used for such processes. L'invention concerne des tensioactifs non ioniques de poids moléculaire élevé comprenant des groupes d'extrémité à terminaison anionique ou leurs sels, un procédé servant à préparer ces tensioactifs et l'utilisation de ces tensioactifs pour diminuer la dureté de systèmes aqueux, adoucir l'eau ou en extraire le sel, retirer des métaux lourds de systèmes aqueux contaminés par ces métaux, ainsi qu'en lavage domestique et industriel, et produits utilisés pour exécuter ces procédés.
