| الوصف: | The displacement adsorption behavior of a poly(methyl methacrylate) (PMMA) and polystyrene (PS) system onto a nonporous silica surface from a carbon tetrachloride solution was studied by utilizing the ESR method. The fractions of train segments for these polymers were determined from ESR spectra analyses; these values were compared with those of the individual adsorption. When PS was preadsorbed onto silica surface and PMMA solutions of various concentrations were added, the amount of PS desorbed from silica surface was proportional to an increase in the initial concentration of the PMMA solution; at the final concentration, PS was completely replaced by PMMA. This phenomenon was due to the stronger interaction of PMMA with the silica surface arising from its polar character, and the greater hydrogen bonding ability. The amount of adsorption for PMMA, which saturated the silica surface, was lower than that when adsorbed on silica surface individually. The adsorbed PMMA formed a more compressed polymer lay... |
