The invention relates to a hydrophobically modified cationic copolymer that comprises at least three different structural units. The water retention in aqueous building material systems on the basis of hydraulic binders, such as cement, can be greatly improved especially in combination with the use of anionic surfactants and even in the event of high salt loads.
