Comparative Study Between New Polyacrylamide Based Copolymer Poly(AM-4VP) and a Cationic Commercial Flocculant: Application in Turbidity Removal
In the present work, adiabatic copolymerization allowed us to synthesize two poly(AM-4VP) (s) copolymers with various macromolecular weights as determined by viscosity measurement. The 1H-NMR was used for copolymer’s structure verification. UV–V
Cationic polyacrylamide, is a white powder water -soluble polymer which is copolymerized by cationic monomer and acrylamide. It has the function of decolorizing, adsorbing, turbid eliminating and bonding. It generate a good flocculation and can

ANIONIC POLYACRYLAMIDE. Composition: Negatively charged copolymers of acrylamide are widely used as retention aids and dry-strength resins. However, different molecular mass ranges are used for these two roles. Anionic acrylamide copolymer reten
Understanding the impact of cationic polyacrylamide on anaerobic digestion of waste activated sludge - ScienceDirect
To further understand the impact of cPAM on anaerobic digestion, the modified Gompertz equation was employed ().Three kinetic parameters, i.e., maximum methane yield potential (Mm), methane production rate (Rm), and lag phase time (λ), were
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for
Biodegradation of Polyacrylamide and Its Derivatives
Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous
Cationic polyacrylamide‐grafted starch (St‐g‐CPAM) flocculant was prepared by using corn starch and acrylamide (AM) as monomers, dimethyl diallyl ammonium chloride (DMDAAC) as cationic monomer through solution polymerization.The effects of

- Who are the leading companies in the polyacrylamide market?
- SNF Floerger Group (France), Kemira Oyj (Finland), BASF SE (Germany), China National Petroleum Corporation (China), and Anhui Jucheng Fine Chemicals (China) are the leading companies in the polyacrylamide market. These companies are expected to account for a significant market share in the near future.
- How much does polyacrylamide cost in the US?
- North America The prices of Polyacrylamide declined in the USA market during the third quarter of 2025, with cost ranging at USD 2252/tonne Polyacrylamide Anionic Grade FOB Texas with a quarterly decline of 11.1% as per recorded by ChemAnalyst pricing team data.
- What is the largest segment of the polyacrylamide market?
- Water treatment was the largest segment of the market, owing to the increasing demand for polyacrylamide from the water treatment industry. The global polyacrylamide market has been segmented based on types, such as anionic, cationic, and non-ionic, among others.
- How is polyacrylamide produced?
- Commercially, PAM is produced by hydration of Acrylonitrile (ACN) to produce Acrylamide and then cross-linking polymerization of Acrylamide that produces PAM. During production, Acrylamide is always advised to be handled with care due to its high toxic nature, although after polymerization polyacrylamide become non-toxic.
