HYDROPHOBICALLY MODIFIED CATIONIC COPOLYMERS |
| 摘要 |
<p>The invention relates to a hydrophobically modified cationic copolymer which has at least three different structural units. Particularly in combination with anionic surfactants, a considerable improvement in the water retention in aqueous building material systems based on hydraulic binders, such as cement, can be achieved even in the case of high salt loads.</p> |
