University of Groningen Synthesis and evaluation of novel
University of Groningen, The Netherlands. This research project was financially supported by Shell and SNF Floerger through the Enhanced Oil Recovery program of the Dutch Polymer Institute (DPI), project nr. 716:
As a synthesis method for the glyoxalated polyacrylamide terpolymers of the present invention, the base copolymer can be reacted with glyoxal at a pH of 7 to 10, or other pH values. The weight ratio of the glyoxal to the base copolymer can range from about 0.01:1 to about 0.6:1, or from about 0.1:1 to about 0.3:1, respectively, or other ratios.

In the present study the performance of a series of star-like branched polyacrylamides (SB-PAMs) has been investigated in oil recovery experiments to ultimately determine their suitability as novel thickening agent for enhanced oil recovery (EOR) applications. Hereby, SB-PAMs were compared with conventional linear PAM. The effect of a branched molecular architecture on rheology, and

Anionic Polyacrylamide, CPAM, PAM manufacturer / supplier in China, offering Anionic Polyacrylamide for Paper Making Industry, SHMP Sodium Hexametaphosphate Food Grade 68%, Flocculant Spfs 21% for Drinking Water Treatment and so on.
Water treatment chemical flocculant nonionic anionic
Anionic PAM is mainly used in minerals selection, metallurgy, coal washing, food, steel, spinning and papermaking industry which involves separation of solid-liquid and waste water treatment. Anionic PAM can also be used for oil well and oil extraction in oil industry, and retention aids and intensifier in papermaking industry.
Anionic Polyacrylamide is water-soluble polymers which is insoluble in most organic solvents, It presents high polymer electrolyte characteristics in neutral and alkaline mediums. With good flocculation, it can reduce the frictional resistance between the liquid and be widely used in mining industries and water treatment etc.
- What is the chemical formula for sodium polyacrylate?
- ?
- ) Sodium polyacrylate (ACR, ASAP, or PAAS), : 233 also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH 2 −CH (CO 2 Na)−] n and has broad applications in consumer products. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water.
- What is sodium polyacrylate?
- Sodium polyacrylate, also known as waterlock, is a sodium salt of poly acrylic acid with the chemical formula [-CH 2 -CH (COONa)-] n and broad application in consumer products. It has the ability to absorb as much as 200 to 300 times its mass in water.
- What is the standard state of polyacrylamide?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
- ) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -).
- Is sodium polyacrylate soluble in water?
- Sodium polyacrylate (9003-04-7) is a commonly used dispersant, also known as 2-sodium acrylate homopolymer, S sodium polyacrylate. It is colorless or light yellow viscous liquid in room temperature, and non-toxic, alkaline, insoluble in organic solvents such as ethanol, acetone but easily soluble in water and aqueous sodium hydroxide.
