Abstract

In this study, we intend to examine the effects of compatibilizer concentration and mixing protocols on both low viscosity and high viscosity matrix blends. The morphology of the compatibilized and uncompatibilized blends were investigated. The compatibilizer was more effective in PE major phase (low viscosity resin) blends. Higher concentrations of the compatibilizer resulted in finer and more uniform dispersion in PE major phase blends. Whereas, for the PS major phase (high viscosity resin) blends, compatibilizer was found not to be effective and in all the three mixing protocols increasing the compatibilizer concentration resulted in coarser morphology. TEM studies indicated that the compatibilizer locates itself in the interfacial region.
