A set of modified expandable polystyrenes was prepared, and the cooling time of the foam samples was measured in the mold during the processing. Polystyrene foam obtained was evaluated with respect to barrier properties. Steady state gas permeation and countercurrent gas binary diffusion were used for the determination of barrier characteristics of the foam. Effective permeabilities and effective diffusion coefficients obtained were correlated with the cooling time of the foams. The conclusive dependence of the barrier characteristics on the cooling time was found.
