Abstract: • Organic vapour and liquid transport properties measured for three biodegradable polymers. • Free volume and glass transition temperature explain the obtained transport properties. • Δ δ = δ pol - δ sol can be used as a tool to predict qualitatively the transport properties. • Plasticization phenomena and work of adhesion have a great influence in liquid permeation. • Vapour sorption measurements corroborate the plasticization and clustering phenomena. In this work an extensive study of vapour and liquid transport properties for various biodegradable polymers has been performed being this kind of studies scarce in literature. For that different techniques have been employed: vapour and liquid transmission rate measurements and vapour and liquid sorption measurements. The study of the vapour and liquid transmission rate of different solvent families allows to shed light on the influence of several factors: nature of the penetrant and polymer, solubility parameter, glass transition temperature and free volume fraction of the polymer, being the last two the factors that play the most important role in the permeability coefficient. Furthermore, based on the solubility parameter, δ , it has been proved that Δ δ = δ pol - δ sol can be used as a tool to predict qualitatively the transport properties. In liquid transmission rate measurements the plasticization and the work of adhesion between the polymer and the solvent influence greatly the obtained results. Sorption measurements have shown that plasticization and clustering phenomena occur. The liquid sorption characterization indicates that both, the molecule size and chemical nature, influence considerably the permeation, obtaining values that expand over 2 decades. Overall, this work aims to provide a deep insight on the transport properties of organic compounds on biodegradable polymers that would allow broadening their applications not only in packaging but also in separation processes.
