The diffusion cell to a Tsvet-800 chromatograph for determining the gas permeability of polymeric materials has been optimised. The oxygen permeability and the carbon dioxide permeability of polymer composites based on polyethylene terephthalate and polybutylene terephthalate have been studied. The optimum compositions, combining high barrier properties and a low acetaldehyde content, have been found.
