Hello,

We are performing advanced molecular simulations programmes to determine the solubility and diffusivity of oxygen, carbon dioxide, and nitrogen gas in poly(ethylene terephthalate) in the melt state but are unable to find any corresponding experimental results in the literature with which to compare our results. Do you have any reference values available for the transport co-efficients of these penetrants through PET at temperatures above 500K applicable at pressures up to 5 bar?

Many thanks,
