Abstract
Claimed is a cationic copolymer and also its use as an admixture agent for building product systems, especially based on calcium sulfate. The copolymers of the invention effectuate accelerated setting behavior in clay-containing as well as non-clay-containing gypsums and they enable uncurtailed water reduction performance by dispersant agents used at the same time with the copolymers. The clay fractions in the gypsum system are masked by the cationic copolymer, and so the building product mixture exhibits properties of a building product mixture not containing clay. The copolymers are used as a formulation and also together with retarders.
