A new and simpler technique is described for the study of the kinetics of adsorption of poly(methylmethacrylale) (PPMA) on a glass surface at 30°C. The kinetics of adsorption were followed gravimetrically by knowing the amount of polymer adsorbed on glass balls at various time intervals. A simple kinetic model for rate of adsorption has been proposed, and from the scheme outlined various adsorption parameters such as adsorption coefficient, surface coverage and film thickness have been evaluated. From the available experimental data, adsorption isotherms have been drawn, and the effect of molecular weight of PMMA on adsorption behaviour has been studied.
