Abstract

DC conductivity effects in thermoplastic polyurethane (TPU)/styrene-acrylonitrile copolymer (SAN) blends were studied by DC conductivity measurements in the temperature range 20-150°C, thermally stimulated depolarization (TSD) currents in the temperature range 20-100°C and AC conductivity measurements over wide ranges of frequency and temperature. The results are discussed in relation to changes in the morphology of the blends induced by composition and temperature variation
