Polyacrylate Polyacrylamide and PHPA. 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.

Rheological Properties of PHPA Polymer Support Fluids
Since the early 1990s, aqueous solutions of partially hydrolyzed polyacrylamides (PHPA) also have been used for the construction of deep foundations in many different countries (e.g., Ata and O’Neill 1997; Lam and Jefferis 2014b). PHPA is a synthetic polymer comprising repeating units of acrylamides and acrylates. Fig.
