Abstract:
1. An amphiphilic polymer composition, obtainable by reacting a) at least one hydrophobic polymer P1 which carries functional groups R b) at least one hydrophilic polymer P2 which carries functional groups R c) with at least one compound V which contains isocyanate groups and, with respect to the isocyanate groups, has a functionality of at least 1.5, where the proportion of the hydrophobic polymer P1 in the amphiphilic polymer composition is from 20 to 68% by weight, the proportion of the hydrophilic polymer P2 in the amphiphilic polymer composition is from 30 to 78% by weight and the proportion of the compound V in the amphiphilic polymer composition is from 2 to 20% by weight, in each case based on the total weight of polymer P1, polymer P2 and compound V.
