Abstract :
A new guest-host polymer was prepared from amorphous teflon AF and an azomethine dye and investigated by dielectric spectroscopy. The spectra show a relaxation with an activation energy of 0.71 eV which is attributed to the chromophore and which can be described with a Cole-Cole function
