Abstract
Adsorption and desorption rates at high surface coverage are reported for poly(methyl methacrylate) (PMMA) adsorbed from dilute carbon tetrachloride solution (1 mg·mL-1) onto a single silicon oxide substrate at 30.0°C. The method of measurement was infrared spectroscopy in attenuated total reflection. The polymer fractions studied were deuterio (d-PMMA) and protio (h-PMMA) with matched degrees of polymerization Nw ≈ 570 and 640, respectively. No adsorption isotope effect was expected, nor noted experimentally. The rapid adsorption of d-PMMA onto the initially bare surface was followed for 1 h, at which time the ambient solution was changed either to a solution of h-PMMA or to pure CCl4.
