The kinetics of adsorption of poly(butyl methacrylate) from individual solutions and mixtures with polystyrene in carbon tetrachloride and the structure of adsorption layer

The kinetics of adsorption and the structure of the adsorption layer of poly(butyl methacrylate) obtained from its individual solutions in carbon tetrachloride and from its mixture with polystyrene were studied by the IR frustrated multiple internal reflectance (FMIR) spectroscopy. The fraction of bound segments and the diffusion coefficients for the various parts of adsorption kinetic curves were calculated. The variation of these parameters in the crossover point is associated with the change in the adsorption mechanism. Polystyrene added to a solution affects the structure formation of a system, the kinetics of adsorption, and the structure of the adsorption layer.
