Competitive Effects in Polymer Adsorption and Exchangeability of Adsorption Layer [PDF]
Bulletin of the Chemical Society of Japan, 1983 Abstract Critical experimental data on competitive adsorption and exchangeability of adsorbed polymer are produced under the various conditions using the gel permeation chromatography technique. It is apparent that the competitive effects and the exchangeability were found to depend not only on the molecular weight of the polymer, but ...
