Based on numerous previous studies, it will show how the permeability of gases (or organic vapours) depends strongly on the polymer structure (degree of crystallinity, thermal and mechanical histories), on the penetrant size and nature as well as on the conditions of temperature and pressure. %G English %2 https://ifp.hal.science/hal-02053930/document %2 https://ifp.hal.science/hal-02053930/file/klopffer_v56n3.pdf %L hal-02053930 %U https://ifp.hal.science/hal-02053930 %~ IFP %~ OGST
