The present invention relates to cationic copolymers, processes for the preparation of these cationic copolymers, and the use of these cationic copolymers as dispersants for geopolymer binder systems. The knowledge underlying the present invention is that the cationic charge of these cationic copolymers is due to the presence of certain cyclic groups and / or polyvalent cationic groups, It is stable against Hoffman desorption that occurs at high pH values. Furthermore, the dispersing action of the cationic polymer can be further enhanced through the addition of a polyvalent anion. |
