Case II diffusion in the PVC and acetone system.
Abstract
This paper describes how nuclear magnetic resonance (NMR) has been used to study case II diffusion of acetone into PVC. NMR is supported by Ion Beam Nuclear Reaction Analysis and Gravimetric Analysis. A series of experiments with different PVC exposure times to acetone vapour have shown the observable physical characteristics of case II diffusion. Experiments in the temperature range 20-50 degrees C have yielded the temperature dependence of the front velocity and the T2 values of the acetone and PVC components.
