| titleOfInvention | Methods to reduce organic impurity levels in polymers and products made therefrom |
| abstract | Various methods are described for preparing dry water-soluble polymers with reduced organic impurity content by combining water-soluble polymer in water with at least one dry polar solvent to form a mixture that separates into a first layer comprising a majority of the solvent and water and a second layer comprising a majority of the polymer, then separating the layers and drying the second layer to obtain a solid comprising the water-soluble polymer. Further, or solid polymer products having reduced organic impurity levels and/or moisture content are also described. |
