Thermoplastic elastomeric blends of Polystyrene (PS) and Exudated Resin (ER) are prepared by solution casting technique. The nature of solvent diffusion through the prepared blends of Exudated Resin and Polystyrene of different compositions are studied at various temperatures. Swelling experiment has been conducted in benzene as the solvent to investigate the solvent resistance properties of these blends. The important parameters such as diffusion,...
