The main objective of this work is to illustrate miscibility, when formation of poly blends occurred in different solvents. Isothermal evaporation method was used to achieve poly blends of poly styrene and poly vinyl acetate (PS: PVAc).The FTIR spectroscopy results revel that there are miscibility exists. For these blends with different solvents, electrical conductivity and dielectric constant were measured at different temperatures (313K, 323K, 333K and 343K) and at the different frequencies (1 KHz to 10MHz) using 4284 LCR meter. It is found that ac conductivity of polyblends thin film varies with temperature for all values of frequencies and it varies with increase in frequencies at constant temperature. The dielectric constant also varies with the increasing of the temperature of polyblends.

Keywords: Solvents; Polystyrene (PS); Polyvinyl acetate (PVAc); Miscibility; AC Conductivity; Dielectric Constants.
