Abstract
The present invention relates to cationic copolymers, a process for the production of these cationic copolymers and the use of these cationic copolymers as dispersants for geopolymer binder systems. These cationic copolymers where the cationic charge is due to the presence of certain cyclic and/or polycationic groups are stable towards Hoffmann elimination that would otherwise occur at very high pH values. Moreover, the dispersing effect of cationic polymers can be further enhanced through the addition of polyvalent anions.
