Abstract : Positron Annihilation Lifetime Spectroscopy is used to determine the free volume content in the blends of SAN/PMMA and PS/PVC. Though the free volume data indicate the miscible/immiscible nature of the blends, the extent of miscibility for different weight compositions is not forthcoming. Therefore the hydrodynamic interaction parameter α which accounts for the excess friction between the constituents of the blend system is evaluated for this purpose. The SAN/PMMA system produces a maximum α of -209 at 20% of PMMA concentration while PS/PVC almost zero. It appears sound that hydrodynamic interaction parameter, α, is a suitable parameter to understand the composition dependent miscibility level in polymer blends.
