Research paper thumbnail of Sample-dimension effects in the sorption of solvents in polymers — a mathematical model

A mathematical model is developed for the coupled swelling-diffusion phenomenon in the polymer sample, which allows the prediction of such sample-dimension effects. Five different kinds of behavior are predicted for a given polymer-solvent pair, and the corresponding size bounds are related to the relevant physicochemical properties of the system. Comparison with a large body of literature data is satisfactory.
