Abstract:
A composition includes a polysaccharide graft polymer composition and 2-phosphonobutane-1,2,4-tricarboxylic acid. In one embodiment, the polysaccharide graft polymer composition includes a polysaccharide residue present in an amount from approximately 5% to approximately 90% by weight of the polysaccharide graft polymer composition and a residue of acrylic acid, methacrylic acid or a combination thereof present in an amount from approximately 10% to approximately 75% by weight of the polysaccharide graft polymer composition.
