TSC in PET containing ferrocene units

It is shown that a prolonged sample of PET containing a metallocene compound forming by means of electric field of several hours duration results in additional structural effects that are not well investigated as yet. A similar problem was also encountered at TSC measurements in polyimide and polystyrene films. This problem calls for further investigation when taking into account the possibility the film may be employed in the presence of a strong electric field and high temperatures.
