Systematic measurement of dielectric constant (ε) and loss (tanδ) on powder pressed pellets of MH and MAA copolymers in composition 10/90, 20/80, 50/50 have been carried out in the frequency range 200Hz-100kHz and in the temperature range from room temperature to 180oC covering through the glass transition temperature, Tg. Two sets of relaxation peaks one slightly above room temperature and the other slightly above Tg are noticed from tanδ versus temperature curves for different frequencies. The peaks are attributed to β- and α- relaxations. Further the peaks shift towards higher temperatures with increase of MH content in the copolymer. The enhanced dielectric behavior is observed in the case of MH-MAA (50/50). The results are discussed in the light of increase in MH content in the copolymer.
