Patent ID: 7923489

Claim:
A hydraulically settable building material comprising an amphiphilic polymer compound prepared by the process of: a) reacting a di-, tri- or tetraglycidyl compound (A) with an optionally unsaturated reactive component (B) comprising C 8 -C 28 -fatty acid, a C 8 -C 28 -alcohol or a secondary C 8 -C 28 -amine, and b 1 ) allowing the reaction product from stage a) to react further first with b 1α ) an aliphatic or aromatic polyisocyanate compound (C) b 1β ) and thereafter with a polyalkylene oxide compound (D) having the formula (I) wherein R 1 is H, a linear or branched and optionally unsaturated aliphatic hydrocarbon radical having 1 to 12 C atoms, R 2 is a linear or branched and optionally unsaturated aliphatic hydrocarbon radical having 1 to 30 C atoms or phenyl; m is from 0 to 250; n is from 3 to 250; and x is from 1 to 12; and the ethylene oxide or higher alkylene oxide units can be arbitrarily distributed in the polyalkylene oxide compound (D), and b 1γ ) reacting the reaction product from stage b 1β ) with a component (E) which is reactive with isocyanates and has at least one OH, NH 2 , NH or SH group, or b 2 ) allowing the reaction product from stage a) to react to completion with the reaction product of component (C) with component (E) and optionally (D) and (C), or b 3 ) allowing the reaction product from stage a) to react to completion with the reaction product from component (C) and component (D) and optionally (C) and optionally the reaction product of component (C) and component (E) and optionally (C).
