THE PECULIARITIES OF ADSORPTION-KINETICS OF MONODISPERSE SAMPLES OF POLYSTYRENE AND THEIR MIXTURES ON A METAL PLATE FROM SOLUTION

The models of competitive and substitution adsorption of a mixture of monodisperse polymer samples on a metal plate from solution are report ed. The proposed mathematical model makes it possible to calculate the rate constants of polymer adsorption and desorption, as well as the s ubstitution constant of a low-molecular-weight polymer sample for a hi gher-molecular-weight sample. The mathematical model was consistent wi th the experimental data on competitive and substitution adsorption of polystyrene monodisperse samples on a platinum plate from a solution in theta-solvent (trans-decaline at 20.4 degrees C).
