<p>A process for hydrolyzing and neutralizing a crosslinked polymer of maleic anhydride and a C1-C5 alkyl vinyl ether, and, optionally a hydrophobic monomer, in anhydride form substantially instantaneously in water at room temperature, which comprises reacting about 0.1-4 % by weight of the crosslinked polymer in water at room temperature with ammonium hydroxide base, with stirring, to form a gel solution.</p> |
