Beschreibung
Zusammenfassung:	The invention relates to a process for preparing a polymer by free-radical polymerization of at least one ethylenically unsaturated monocarboxylic acid and/or a salt thereof,at least one ethylenically unsaturated dicarboxylic acid and/or an anhydride and/or a salt thereof,in the presence of hypophosphorous acid and/or a salt thereof. The invention also relates to a polymer composition obtainable by this process. The invention also relates to the use of such a polymer composition as detergent additive, e.g. as dispersant, scale inhibitor or sequestrant for laundry detergents.
