An improved method for the preparation of uniform dispersions of non‐stoichiometric polyelectrolyte complexes on the basis of maleic acid copolymers and poly(diallyldimethylammonium chloride) was developed. The dispersed particles showed a narrow size distribution on the nm scale and were used as model systems for the investigation of their adsorption on different model surfaces. A combination of ATR‐FTIR, SPR, ellipsometry and SEM was useful for the monitoring of the adsorption process of individual colloid particles and may lead to a quantitative description of the adsorption process. For a better understanding of the underlying principles and interactions organic model surfaces which meet the requirements of the different methods are required.
