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.
The global polyacrylamide market size was valued at USD 4.5 billion in 2018 and is projected to expand at a CAGR of 6.2% from 2019 - 2025. Surging demand for the product across various application industries, including waste water treatment, oil recovery, paper making, and food and beverage, is expected to propel the industry growth

Polyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or PAM [-CH 2 CH(CONH 2)-]. It is a non
We has one chemical polyacrylamide production line with the annual output of 10000 tons; Two front hydrolysis lines 3000 tons anionic, 1000 cationic and 500 nonionic separately; it also a polyaluminium chloride oil
Key Difference – Acrylamide vs Polyacrylamide Acrylamide and Polyacrylamide are two amide molecules, but acrylamide is a single molecule and Polyacrylamide is a polymer (a large molecule which is formed by monomers) which is produced from the monomers (a molecule that can be bonded to other identical molecules to form a polymer) of acrylamide. In other words, the key difference between

Polyacrylamide (PAM), 94% (for water treatment, 55% pulp and paper production, 23% mineral processing, 8% enhanced oil recovery, 4%, miscellaneous, 4%) N-methylolacrylamide and other monomers, 6%. Source: ICIS Chemical Business MARKET PERSPECTIVE. PAM-based flocculants consume all but about 6% of acrylamide monomer.
Acrylamide is a chemical that commonly used in industry to prepare polymeric material that used in many products in contemporary living known as polyacrylamide. Acrylamide can be present in either monomer (single unit) or polymer (multiple units that joined together by chemical bonds) (The Merck Index, 1996).
Polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a compound obtained by the hydration of acrylonitrile. Acrylamide is usually dissolved in water; it has toxic effects on the nervous system and must be
These polymers are used widely in water treatment, petroleum production, pulp and paper production, mineral processing, and numerous small-volume applications. The bulk of the production of acrylamide is concentrated mainly in China, Western Europe, and the United States, with China accounting for over 60% of the global production capacity.
15.2.5 Polyacrylamide. Polyacrylamide is a water soluble polymer prepared from an acrylamide monomer. Polyacrylamides are part of diverse class of water soluble and water swellable polymers. They possess hygroscopic properties which has led to their application in dewatering and related applications.
For example, 4 % monomer (4g/dl) solution has no polymer initially. At 50 % conversion, 2 g/dl of monomer and 2 g/dl of polymer coexist. At 100 % conversion, monomer has been completely depleted. Only 4 g/dl of polymer exists. Free radical polymerization of acrylamide: In the case of the polymerization of acrylamide to polyacrylamide, the
Trace amounts of acrylamide remain in polyacrylamide. Acrylamide is found in in lotions, powders and creams. ,, Daily exposure to acrylamide through cosmetics may exceed the amount that would result from smoking a pack of cigarettes a day (.95 vs .67micrograms/kg of body weight per day).

The hydrolysis of polyamides has been studied in buffered acid solution at 110°C. at an amide concentration of 0.05 M .In the case of polyacrylamide, the reaction was carried out in acetate buffer at different values of the ratio r (acetic acid/sodium acetate). The initial velocity is low and is proportional to the concentration of acetic acid; the rate constant is equal to 2.6 × 10 −6
U.S. patent 3,631,104 (1971) C. E. Habermann, B. A. Terfertiller (Dow Chemical) Polymerization of polyacrylamide. If heated above the melting point, acrylamide may polymerize. Caution, the reaction is exothermic. Acrylamide may be polymerized in water at concentrations from 8- 20%, using AIBN, peroxide, or redox catalysts.
