Iron(III)-complexing agent for stabilizing comb polymers in mineral binding agents

摘要

The invention relates to compositions comprising a comb polymer and a Fe(111)-complexing agent X, which is selected from the group comprising thiocyanates, condensed phosphates, amines, amino acetic acids, oxycarboxylic acids and compounds of the formula (V). In addition, the invention relates to a method for stabilizing comb polymers in the presence of Fe(III) using such Fe(111)-complexing agents X.
