The phase behavior of polymeric materials is understood through glass transition temperature. It is a temperature boundary above which the polymeric material is soft and viscous, and becomes hard, brittle, and glassy below this temperature. In the present work, PS/PMMA immiscible polymer blend samples are studied at different compositional ranges. Thermal transport properties of PS/PMMA polymeric blends were measured , from room temperature to 120°C. Variation in thermal conductivity ...
