Polyacrylamide PAM is a general designation of homopolymers of acrylamide or copolymerized with other monomers. It is one of the most widely used water-soluble polymers. Because the structural unit of polyacrylamide contains amide group, it is easy to form hydrogen bond, which makes it have good water solubility and high chemical activity. It is easy to obtain a variety of modifiers with branch chain or network structure by grafting or cross-linking. It is widely used in oil exploitation, water treatment, textile, paper making, mineral processing, medicine, agriculture and other industries, and it is called "one hundred industry auxiliaries". The main application fields in foreign countries are water treatment, paper making, mining, metallurgy, etc.; at present, the largest consumption is in oil production field in China, and the fastest growth is in water treatment field and paper making field.

Use properties
1. Flocculence: PAM can make the suspended matter through the electric neutralization, bridge adsorption, flocculation.
2. Adhesiveness: it can play a role of adhesion through mechanical, physical and chemical functions.
3. Resistance reduction: PAM can effectively reduce the friction resistance of the fluid, and the resistance can be reduced by 50-80% by adding a small amount of PAM into the water.
4. Thickening property: PAM has thickening effect under neutral and acid conditions. PAM is easy to hydrolyze when pH value is more than 10. The thickening will be more obvious when the structure is semi reticular.
