Abstract: A description is given of electrosterically stabilized polyurethane resins having an improved profile of properties, obtainable by a) preparing a hydrophilic and solvent-free macromonomer (A)(ii) with monomodal molecular mass distribution, by a1)reacting 50 to 100 parts by weight of a hydrophilic alkyl- or arylpolyalkylene glycol (A)(i) with 1 to 100 parts by weight of a polyisocyanate component (B)(i) optionally in the presence of a catalyst in the absence of solvents, and subsequently a2) reacting the uniform preadduct from stage a1) completely with 0.
