  • Difference Between Acrylamide and Polyacrylamide |

    2020-12-7 · Acrylonitrile is polymerized to form polyacrylonitrile which is then partially hydrolyzed to form acryla-mide and acrylic acid groups along the polymer chain (see Figure 16). These polymers are referred to as PHPA, (partially hydrolyzed polyacrylamide), and are used as clay extenders, flocculants, and encapsulating colloids. Figure 16.
