The sub‐T storage of PET(polyethylene terephthalate) and PEN( g polyethylene naphthalate) has been investigated by means of TSC(thermally stimulated current) and DSC(differential scanning calorimetry). An apparent activation energy of sub‐T storage equal to one fourth of the activation energy g of glass transition has been obtained.
