The diffusion and solution of hydrogen and neon have been measured in a series of polyvinyl chloride sheets containing various concentrations of plasticiser. Diffusion coefficients DL and DE were determined using the time-lag and 'early approximations' methods respectively, and permeability coefficients f from the steady-state permeation rate. Dynamic (op,62) and static (os) solubility coefficients were respectively determined from permeation and equilibrium measurements.
