Abstract
The adsorption/desorption kinetics for individual polymers and polymer mixtures of the water-soluble associative polymers with molecular weights of 12, 62, and 100 kg/mol onto a SiO2 planar substrate have been studied by ellipsometry at room temperature under flow conditions. Equations were derived to predict behaviors of the adsorption/desorption kinetics and dynamic surface tension onto planar surface for any times. It is shown that the rate of adsorption/desorption kinetics under nonflow conditions is significantly less than the one under flow conditions due to the convective–diffusive mass transfer to an interface.
