Polyacrylamide - an overview | ScienceDirect Topics
Polyacrylamides are not biodegradable and limiting the molecular weight or incorporation of biodegradable groups must be considered. Presence of any acrylamide monomer in the polymer formulations as a result of the thermal or photo degradation of polyacrylamide or as the possible residual of the polymerization process is a concern associated

Polyacrylamide with low molecular weight - Henkel
Accordingly, the present invention relates to a polyacrylamide-containing adhesive composition which is characterized in that it contains a polyacrylamide with a very low molecular weight of 2,000 to 8,000 g/mole and preferably 3,500 to 5,000 g/mole, as determined by gel permeation chromatography (GPC), and in that the polyacrylamide has a
1. The use of a polyacrylamide-containing composition, the polyacrylamide having molecular weight of 2,000 to 8,000 g/mole, as determined by gel permeation chromatography, and a Brookfield viscosity of 5 to 500 mPas in the form of a 15% by weight solution at 25掳C, for surface bonding of and/or to water-absorbing or hard surfaces. 2.

PolyDADMAC and polyamines are low-molecular-weight polymers with a high cationic charge density. Polyvinyl alcohol is synthesized by the hydrolysis of polyvinyl acetate in a continuous process.
low molecular weight nonionic polyacrylamide in uzbekistan
Polyacrylamide (MW 10,000) Polyacrylamide (PAM, Mw 10,000) is a low molecular weight nonionic water-soluble polymer used as an additive in CMP slurries, various printing applicatons, and as a flocculant in water treatment. 50% solution in water (packaging size denotes weight of solution).
High molecular weight anionic PAM with 30% surface charge (A-130) was more effective(46% reduction) than those having a high molecular weight and a lower surface charge of 20% (A-110 and A-120

- What is cationic polyacrylamide?
- Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- What is ionic polyacrylamide?
- The ionic forms of polyacrylamide has found an important role in the potable water treatment industry. Trivalent metal salts, like ferric chloride and aluminum chloride, are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate.
- What is the price of polyacrylamide (anionic grade) in 2025?
- Thus, after the conclusion of the first quarter of 2025, PAM prices (Anionic Grade) were assessed at USD 3400 per MT. For the Quarter Ending December 2025 North America The market prices of Polyacrylamide moved in a downward direction in the North American market during the fourth quarter of 2025, as per ChemAnalyst Research Team Data.
