Polyacrylamide Market Size and Share | Industry Statistics - 2027
Cationic polyacrylamide (CPAM) market revenue is forecast to grow at a CAGR of 7.2% from 2025 to 2027. This can be credited to the usage of cationic polyacrylamide as sludge conditioners, for its low dosage requirement, higher efficiency, and
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

- Is polyacrylamide a water soluble polymer?
- Polyacrylamide (PAM) is a synthetic water-soluble polymer, which is also commonly applied as a viscosity modifier in cementitious materials [ 11, 12 ]. Owing to its high molecular weight (up to 30 million) as well as the -COOH and -CONH 2 groups present in its structure, PAM confers thickening properties [ , , , , ].
- Does polyacrylamide hydrolyze under acidic conditions?
- As reported by Muller et al., polyacrylamides undergo hydrolysis under acidic conditions to yield poly (acrylamide-co-acrylic acid). Amide groups will completely hydrolyze under conditions of appropriately low pH, and polymer weight will remain relatively stable during hydrolysis, as the following formula , , .
- Does hydrochloric acid degrade acrylamide based polymers?
- Of the studied solutions, AM-AMPS exhibited the best viscosity maintenance in 10 wt% HCl. The changes in polymer molecular weight indicate that the high concentrations of hydrochloric acid gradually degraded the four acrylamide-based polymers, demonstrating that the modification will have significant effect on their acid resistance.
- Does HBR hydrolyze polyacrylamide?
- It was also reported that HBr acts as a catalyst for the hydrolytic scission of amide bonds, resulting in a scission and MW chain reduction. Muller et al. , proposed that polyacrylamides would hydrolyze under slightly acidic conditions (pH = 4), and reported that the molecular weight of the polymer remained relatively stable during hydrolysis.
