ABSTRACT:
A method for the preparation of aqueous solutions of anionic polyelectrolytes by combining a stream of a high solid content alkenoic acid-alkyl acrylate latex with a stream of aqueous alkali metal hydroxide, mixing the combined streams under low shear conditions and heating the mixture to produce a polyelectrolyte solution.
The use of these steps avoids the formation of high viscosity mixtures or rubber masses which are difficult, if not impossible, to further process into the desired polyelectrolyte solution.
