The sorption and diffusion of water vapor in poly(ethylene terephthalate) (PET) film were measured by applying a thermogravimetric analyzer (TG-DTA), which customarily has been used to detect the weight loss of a sample with the increase of temperature under a given atmosphere. In this case, we dete

Measurements have been made of the solubilities and effective diffusion coefficients at 25ยฐC for carbon dioxide in random and uniaxially oriented samples of poly(ethy1ene terephthalate) and poly(ethy1ene naphthalate) (PET and PEN). Most measurements were made using a double-sided experiment in which

## Abstract The gas barrier properties of a wide range of biaxially oriented polyethylene terephthalate films have been investigated. The permeability and diffusion coefficients for oxygen and water vapor transmissions were determined for films prepared by both simultaneous and sequential biaxial s

The water sorption characteristics of poly(ethylene terephthalate) (PET) amorphous samples of 250 m thickness have been studied at various temperatures in a saturated atmosphere. Concerning diffusivity, one can distinguish the following two domains characterized by distinct values of the activation
