Abstract
The adsorption of poly(ethylene oxide) on mica is promoted by cationic end groups. These cation-terminated polymers adsorb on mica surfaces via ion exchange, resulting in a film of polymer attached to the layer ed silicate. The experimental ion exchange isotherms resemble those fo r small cations, but with a much reduced surface-exchange capacity for the polymeric cations. The number of adsorbed chains decreases with i ncreasing chain length while the mass adsorbed increases. (C) 1997 Aca demic Press.
