Abstract :
ac Conductivity measurements on thin films of PMMA:PVAc polyblends (blend ratio-1:5, 1:2, 1:1, 2:1 and 5:1), grown by isothermal immersion technique, have been carried out in the temperature range 313 K to 433 K and frequency range 200 Hz-2 kHz. The temperature dependence of ac conductivity at all the frequencies, in case of all the blends studied, shows a peak which shifts towards higher temperature with increase in frequency. The ac conductivity has also been observed to increase with frequency. An attempt to explain the observed behaviour and to understand the conduction in PMMA:PVAc polyblends has been made
