Compositions and methods useful as stabilizing dispersions containing paper sizing agents are provided. The dispersions comprise a hydrophobically modified water-soluble polymer having a viscosity average molecular weight less than about 200,000. Dispersions containing sizing agents and other agen ts for treating paper can be made according to the methods of the invention.</S DOAB>
