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 α 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.

 

Key words: Viscosity, polymer blends, poly (methyl methacrylate), poly (vinyl chloride), polystyrene, fourier transform infrared spectroscopy.
