โœฆ Synopsis


A sorption gravimetric technique has been used to estimate the diffusion and thermodynamic parameters of four different VITON fluoropolymers in the presence of five ester molecules. Diffusion parameters have been obtained by assuming the Fickian transport and their concentration dependencies are studied. Fluorine contents of the fluoropolymers have significant effects on the membrane transport characteristics. 0
