## Abstract This work is focused on the glassy dynamics of polymers under conditions of oneβdimensional confinement (in thin films). Several important topics are addressed: (a) preparative factors with large impact on the molecular dynamics of thin polymer films (oxidative degradation, plasticizing
Small molecules in glassy polymers are considered to occupy sites with a distribution of free energies of dissolution. Then their diffusivity depends on concentration and temperature in the same way as it has been derived for hydrogen atoms in metallic glasses. For hydrogen it was shown that the tra
