Polyacrylamide is a high molecular weight polymer with the repeat unit ( -CH_2-CH(OH)CONH- ). It is renowned for its excellent water solubility and gel-forming properties. Commonly used in water treatment, papermaking, and as a thickening agent in various industries, it also plays a crucial role in fields like biomedicine and environmental engineering due to its high viscosity and flocculation capabilities.
