Abstract
A systematic study and interpretation of the transport parameters characterizing the permeation of the noble gases, He, Ne, Ar and Kr through poly(methyl vinyl ketone) and poly(methyl vinyl ether) are presented. The results and correlations are compared with related measurements on poly(methyl acrylate) and poly(vinyl acetate). In general the measurements were conducted above the glass transition temperatures of the respective polymers. The results are interpreted in terms of the systematic variations in the physicochemical parameters of these closely related polymers. Free volume and dipoledipole interactions appear to dominate the observed behaviour and the composite results may be explained in these terms. The size distribution of the fluctuating free volume elements and chain stiffness are also to be considered.
