Abstract
The effect of the variation of the type of solvent responsible for the differences in the swelling kinetics of Polystyrene (PS) and Polyvinyl acetate (PVAc) blends was studied. The results showed that the nature of solvent control or affects the degree of swelling. Also, 1-V characteristics at temperature range of 323-363K shows promising semi conducting ability which appreciated with amount of filler in the polymer-polymer matrix. Key words: Swelling behavior, Polystyrene (PS) - Polyvinyl acetate (PVAc) blends, electrical conductivity, filler composition.
