Polyelectrolyte behavior of Astramol TM poly(propylene imine) dendrimers of five generations, G1‐G5, namely DAB‐ dendr ‐(NH 2 ) x (where x is equal to 4, 8, 16, 32 or 64) was studied by means of potentiometric titration in salt‐free water solutions and also in the presence of a shielding low molecular electrolyte (NaCI). In addition to x outer primary amine groups the dendrimer molecule contains x ‐2 inner tertiary amine groups. The repeating unit, the core molecule and the fifth generation dendrimer structure are shown in the following Scheme.
