Another way to improve the solubility characteristics of hydrophobically associating polymers is through incorporation of water-soluble, ionic monomers into the polymer. Carboxylate functionality has been introduced into RAM polymers by either copolymerization with acrylic acid salt or by a postpolymerization partial hydrolysis of the acrylamide groups. Incorporating about 20 mol% sodium acrylate functionality, significantly improves solubility of these HRAM polymers. Sulfonate groups can be introduced by copolymerizing with a sulfonate monomer such as vinyl sulphonate or 2-acrylamido-2-methylpropane sulfonate, AMPS. We call these polymers SRAM. [Pg.36]
