Alternating-current (ac) conductivity and dielectric relaxation behaviour of a poly(vinyl chloride)/poly(ethyl methacrylate)
polymer blend have been investigated intensively in a frequency range from 1 × 10⁻¹ to 2 × 10⁷ Hz through a
temperature range from 300 to 393 K. The variation of σac of pure and polyblend samples showed a plateau region at
high temperature and low frequency and this plateau region is decreased with decreasing temperature. Values of the
exponent $n$ are less than unity indicative of the correlated barrier hopping for conduction. The values of the exponent $n$
are used to calculate the binding energy (
