Summary

Phase diagram calculations for a mixture of sodium salt of polymethacrylic acid [PMAA] and polyvinyl alcohol [PVA], which are a commonly used dispersant and binder for ceramic systems, predicts phase separation of the polymeric additives in an aqueous solution. A light scattering technique was employed to characterize the polymer interactions. Light scattering rises with polymer concentration and strong light scattering is shown around equimolecular PMAA and PVA levels, which indicates strong polymeric interactions. Light scattering also increases as solution pH goes up. PVA in spray-dried granules was stained and its location and color intensity were explained with light scattering studies.
