Abstract

Water-soluble polymers are being used in the paper coating industry for a variety of purposes including the development of water holding, viscosity control, structure and binder migration control. This study was designed to evaluate the degree that selected types of water-soluble polymers (carboxymethylcellulose, hydroxyethylcellulose, sodium alginate, polyvinyl alcohol and a polyacrylate) influence these properties. The methodology comprised of recently developed techniques in which water holding, immobilization solids and binder migration could all be measured for similar coatings applied on a paper-like porous substrate. The results illustrated that watersoluble polymers affect both the water-loss rate and binder migration, but reduce the immobilization solids. Under the conditions examined, the polyacrylate used was the best polymer for water retention, while the alginate and CMC gave superior binder migration control. Results also indicated that there is a significant correlation between water-loss rate and binder migration.
