Preparation and characteristics of anionic polyacrylamides
Anionic trash showed no interference with the performance of DR-A-PAM in the wet end, while the additive performance was sensitive to calcium ions. Surface plasmon resonance analysis gave useful information on the cellulose-anchoring ability of DR-A-PAM.
COMMERCIAL Polyacrylamides Major manufacturers of acrylamide polymers are BASF, SNF Floerger, Shangdong Tongli , and Kemira. Applications. Poly(acrylamide-co-acrylic acid) and its sodium salts (APAM) are widely used as thickening agent, binder, super absorbent, soil conditioner, filtering aid, flocculating agent, crosslinker, suspending agent, lubricant, and oil recovery agent.
Polyacrylamide - an overview | ScienceDirect Topics
Polyacrylamide gel electrophoretic studies of the water-insoluble phases of the large nerve vesicles and the chromaffin granules have revealed some similarities (Helle & Lagercrantz, 1972; Bartlett, Lagercrantz & Smith, 1976). 16–20 protein bands were reproducibly found in extracts of the large nerve vesicle preparation and six of these were
Water soluble polymers cover a wide range of highly varied families of products of natural or synthetic origin,and have numerous uses. Among these families, synthetic polymers, and more particularly coagulants and flocculants,are used mainly for facilitating the separation of materials in suspension in aqueous media.They

Generally, very high-molecular-weight, anionic polyacrylamides are the most effective coagulant aids. Nonionic or cationic types have proven successful in some clarifier systems. Essentially, the polymer bridges the small floc particles and causes them to agglomerate rapidly into larger, more cohesive flocs that settle quickly.

Reducing Furrow Irrigation Erosion with Polyacrylamide (PAM) The growth characteristics of the acacia were monitored over a two-year period from 2009 to 2010. Polyacrylamides
Dispersion of pigments is a very critical step in the successful preparation of a coating. The dispersant can be one of the most important ingredients in a water borne formulation. Candidate dispersants must function in an acid media. Dispersants which satisfy this criteria would be of an anionic or non-ionic chemical type.
- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
- Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
- What is organic polymer flocculant cationic polyacrylamide (CPAM)?
- The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [ 11, 12, 13, 14, 15 ].
