Zusammenfassung:The present paper reports the investigations on miscibility and thermophysical properties of blend of Poly methyl methacrylate with Polyvinylchloride, prepared by solution casting method. The miscibility of the samples is examined by dynamic mechanical analyzer (DMA) and the thermophysical properties (thermal conductivity ( lambda ) and thermal diffusivity ( chi )) have been measured using the transient plane source (TPS) technique from room temperature to 100 degree C. The results of thermal transport properties of PMMA/PVC blend show an increasing trend of lambda and chi upto Tg, beyond which they show a decreasing trend. The variation of thermal conductivity and diffusivity of PMMA, PVC and PMMA/PVC blend with temperature is explained on the basis of structural changes of the sample and mean free path of the phonons.
