Abstract

The effect of polymer-polymer interactions on the miscibility of PVC/PMMA and PS/PMMA blends were
studied in a broad composition range using viscosity and FTIR techniques. From the viscometric data,
the presence of attractive forces among different polymers was evaluated according to Sun et al. (1990),
by the determination of parameter. Based on sign convention involved in the criterion, PS/PMMA
system was found as immiscible while miscibility was observed in PVC/PMMA blend. FTIR analysis also
supports the viscometric data.
