Water-soluble graft polymers are described which are characterized by a) radical grafting of a polyalkylene oxide of the general formula (I) in the R¹ = -H, -C n H 2n + 1 , -C₆ H₄-C n H 2n + 1 , - (CH-R²) m NHR², - (CH-R²) m OH, - (CH-R²) m -COOH, -CO-R⁵ R² = -H, -CH₃, -C₂H₅ R³ = -H, -C n H 2n + 1 , -C m H 2m -SO₃ Na, - (CH-R²) m NHR², - (CH-R²) m OH, - (CH-R²) m -COOH, -CO -R⁵ R⁴ = -H, - (CH-R²) m -COOH, -CO-R⁵ R⁵ = -C m H 2m + 1 , -C₆H₅, - (CH-R²) m -COOH, -C₆H₄ -COOH n = 1 - 18 m = 1 - 5 x = 2 - 200 y = 0 or 1 with an ethylenically unsaturated mono- or dicarboxylic acid or its anhydride and then b) derivatization with a primary or secondary amine and / or alcohol have been prepared. n n n These graft polymers are suitable as dispersants for water-containing inorganic binders such as e.g. Cement, plaster, anhydrite. |
