Abstract
The diffusive transport of several simple gases in four thermoplastic elastomers was measured. Certain anomalies were observed with the larger-sized penetrants, namely Ar and N2. It appears that these gaseous penetrants can distinguish between the rigid and flexible regions of certain block copolymers, the effect being more pronounced for the gas with the larger molecular diameter. A model is proposed and discussed which is qualitatively consistent with the observed behavior.Keywords
