Polyacrylamide
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

Polyacrylamide - an overview | ScienceDirect Topics
Polyacrylamide (PAAM) forms soft, cationic nondegradable hydrogels consisting of entangled polymer chains tethered to one another via cross-linkers [175]. Its hydrophilic nature results in a high capacity for swelling and tendency for cell
Amphiphilic polymers are a type of polymers formed by adding a small amount of hydrophobic groups to the HPAM molecular chain (see the structural formula shown in Fig. 5 (b)) [34–36]. Luo et al. have synthesized a variety of amphiphilic polymers

- Who bought polyacrylamide flocculant?
- Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).
- What are polymers used in flocculation?
- Polymers are chemicals used in flocculation. Flocculation is the process of agglomerating destabilized particles into bigger flocs. In wastewater flocculation and sludge treatment, colloidal particles are flocked in order to aid their removal or to help sludge dewatering.
- What are water soluble polymer flocculants?
- Abstract Water soluble polymer flocculants are important constituents of solid–liquid separation units for the treatment of a variety of process-affected effluents. The systematic development of a ...
- What are the types of industrial polyacrylamides?
- The types of flocculants, in other words industrial polyacrylamides, are cationic, anionic or nonionic polyacrylamides. Kemira’s polyacrylamides of wide range of charge and molecular weight are sold in dry powder or emulsion format and have excellent performance.
