The degradation of PAM/HPAM can occur in the field due to heat and ultraviolet radiation, which results in the hydrolysis of polymer and release of small amount of acrylamide monomers (Wen et al. 2010 ). Due to the high viscosity of HPAM, it forms emulsions in oil and remains stagnant, making it difficult to separate oil and water.
