Non-isothermal currents in polymer samples associated with temperature gradients

In this note we shall present results of measurements of non-isothermal currents in non-prepolarized samples of polymethyl methacrylate (PMMA) and polytetrafluoroethylene (PTFE). It will be shown that the currents are associated with reorientations of dipoles due to temperature gradients existing during cooling and heating of the samples.
