The equilibrium structure of a monolayer formed by long polyelectrolyte chains adsorbed at the interface between a charged surface and a dilute polyelectrolyte solution is analysed. The self-consistent field equations for the configurational probabil

The binding of dodecyltrimethylammonium bromide (DTAB) to poly(maleic acid-co-alkyl vinyl ether) has been investigated by means of potentiometry and fluorescence probing, using pyrene as a probe, as a function of the length of the copolymer alkyl cha

The adsorption on silica of diblock copolymers of styrene and 2-vinylpyridine with large pyridine blocks from toluene solutions at concentrations below the cmc was investigated by using radiolabeled polymers. Fast adsorption was observed for initial

The adsorption of hydrolyzed polyacrylamide (HPAM) dissolved in distilled water onto sorbents with (SiO)2AlOH and SiOH surface sites was investigated as a function of pH and degree of hydrolysis τ (concentration ratio [COOH]/([CONH2] + [COOH]) of ca

We have studied the irreversible aggregation of colloidal polystyrene spheres using a particle counter technique. The mode of cluster growth is found to be modelled by a reaction limited aggregation process. Elementary grains disappear by collision w

In the present paper, we report on the rate of exchange of 3H-labelled polymers in the adsorbed state with non-labelled polymers in the solution. The method consisted in carrying out preliminary adsorption with radioactive polymers, and subsequently

The size distribution of negatively charged polystyene latex particles flocculated in the presence of 0.15 M NaCl or in the presence of poly(4-vinylpyridine) was measured using an automatic particle counter. The time evolutions of the size distributi
