A grafted polyvinyl alcohol polymer has a balance between hydrophilicity and hydrophobicity. The grafted polyvinyl alcohol polymer has a chemical functionality that allows for adsorption onto the pulp fibers, polymer film formation upon drying, repelling water upon wetting, polymer film swelling and breaking for prolonged wetting by water. When incorporated into paper products, the polymer can provide a paper having improved wet strength, temporary water repellency, and/or is dispersible in aqueous solutions.

The invention relates to the composition of core-shell impact modifiers, in particular those with a high T.sub.g core, a low T.sub.g inner shell and a high T.sub.g outer shell, synthesized in such a way to have a unique concentric morphology and/or a combination of high rubber loading and low particle size and/or require only a low surfactant level. The incorporation of these impact modifiers into polymeric compositions allows for a novel combination of high impact while retaining high gloss or a combination of high impact while retaining low haze in the presence of water at elevated temperatures. These impact modifiers also allow excellent efficiency in their use- allowing for excellent impact to be achieved at low loadings.
