Abstract
Polysaccharide graft copolymers are prepared by a water-in-oil emulsion polymerization process in which the polysaccharide and water-soluble monomer are emulsified in an oil phase containing emulsifying agents and polymerized therein. The resultant emulsion polymers are in stable form and may be used directly, for example, as adhesives for prepasted wallpaper, or may be inverted into aqueous systems and used for their thickening or flocculating properties.
