in the production of polyacrylamide. Both acrylamide and polyacrylamide are used mainly in the production of flocculants for the clarification of potable water and in the treatment of municipal and industrial effluents. They are also used as grouting agents in the construction of drinking-water reservoirs and wells (IPCS, 1985).

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
Polyacrylamide has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale. It is widely used in papermaking, mining, coal washing, metallurgy, oil exploitation and other industrial sectors and is also a important chemical for water treatment. Figure 1 The synthetic route of polyacrylamide.
Polyacrylamide is a polymer that is used in a wide variety of cosmetics and personal care products due to its ability to form a thin coating on the skin, hair, or nails. Origin Polyacrylamide is a polymer (long chain) of acrylamide monomers. The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or …

< Sponsored Listing Characteristics: Polyacrylamide (PAM) is water-soluble polymers, which is insoluble in most organic solvents, with good flocculation it can reduce the frictional resistance between the liquid. Our products by ion characteristics can be divided into anionic, nonionic, cationic types. It can easily absorb moisture and become the block matter, thus it should be kept in dry

Water-absorbingbeads sold as children's toys and used in vases and gardens are a growing problem among young children. The non-toxic water beads are called jelly beads, water orbs, hydro orbs, polymer beads andbeads. When the tiny hard plastic balls are placed in water, they can grow up to 200 times their size.

Polyacrylamide is also used in water, sewage and waste treatment, oil recovery, ore processing paper making, and to make permanent-press fabrics, to synthesize dyes, contact lenses, and in the construction of dams, tunnels and sewers (Habermann 2002). [7] Polyacrylamide is also present in cigarette smoke.
Moreover, it is also used as a chemical intermediate in the production of N-methylol acrylamide and N-butoxyacry. It is also used in some potting soil as well. Polyacrylamide: Polyacrylamide is mainly used to flocculate solids in liquids. This process is applied in water treatment, screen printing, and paper making.
