Polyacrylamide | Tradeasia International
Polyacrylamide (PAM) is a water-soluble polymer made up of acrylamide subunits. It has a unique effect to increase the viscosity of water or promote the flocculation of particles present in water, it can also reduce the frictional resistance between the liquid.

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
Anionic polyacrylamide - wastewater treatment chemicals
Description. Anionic polyacrylamide is the kind of wastewater treatment chemicals which is water-soluble linear polymer synthesized with high degree of polymerization.Anionic polyacrylamide powder is easily soluble in water and almost insoluble in common organic solvents such as benzene, ether, lipids and acetone. Anionic polyacrylamide molecular chain contains a certain amount of polar groups
The chemical formula for acrylamide is C 3 H 5 NO, and the molecular weight is 71.08 g/mol. (2) Acrylamide occurs as a white, crystalline solid or flake-like crystals and is highly soluble in water. (2,3) Acrylamide is odorless. (2) The vapor pressure for acrylamide is 0.007 mm Hg at 25 掳C, and its log octanol/water partition coefficient (log
Water Soluble Polymer Flocculants: Synthesis
Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide
Hydrophilic polymers contain polar or charged functional groups, rendering them soluble in water. Within this section, most hydrophilic polymers are grouped by the chemistry of their structure. For example, acrylics include acrylic acid, acrylamide, and maleic anhydride polymers and copolymers.

Polymers for conformance improvement - PetroWiki
Pendant water-soluble chemical groups (e.g., amide groups) on the molecule render the polymer molecule to be soluble in water. Synthetic polymers have emerged to become the predominant and preferred polymer type for use in commercial oilfield conformance improvement operations because of the inherent chemical and biological stability of
The copolymer of acrylamide (AM) and 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) was synthesized through radical solution polymerization by potassium persulfate as initiator. By changing the AMPS feed ratio from 10 to 70%, and keeping other reaction conditions constant, different copolymers were synthesized. The techniques of Fourier transform infrared (FTIR) and nuclear magnetic
- How can zwitterionic polymers be synthesized?
- Zwitterionic polymers can be synthesized by copying monomers containing cationic and anionic functional groups, as shown in Table 1 [5, 24]. The initial synthesis of polymerizable betaine monomers, followed by copolymerization with other functional monomers is an achievable approach [54, 58].
- How are zwitterionic compounds assembled?
- Zwitterionic compounds are often assembled via a complex multi-step synthesis (Scheme 6, cf. also Figure 13). The key step is typically the coupling of the anionic and the cationic groups, for which manifold pathways have been employed, including enzymatic reactions in the case of the ammoniophosphates (I in Figure 1).
- What are zwitterionic based topological polymers?
- With the development of polymerization technology, in order to meet the ever-increasing performance requirements of polymer materials, a variety of zwitterionic-based topological polymers, such as block-based, star-shaped, hyperbranched, dendritic, brush and cyclic polymers have sparked the attention of researchers’.
- Are zwitterionic polymers a problem?
- With the continuous expansion of applications, problems with zwitterionic polymers have been exposed. The current structure of zwitterionic polymers cannot meet the requirements for further development, and more zwitterionic polymers with new-type ideal structures need to be synthesized.
