Polyacrylamide degradation and its implications
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21

Polyacrylamide flocculant for drilling fluid in Iran marketing
Polyacrylamide in Oilfield Sinofloc Chemical. Polyacrylamide is a versatile chemical treatment agent in oilfield. In oil extraction it could be used as a flooding agent, water shutoff regulator, drilling fluid regulator, fracturing fluid additives, especially in cementing, completion and workover. Sinofloc Polyacrylamide (PAM) Used as Drilling
Polyacrylamide, PAM, anionic polyacrylamide. Polyacrylamide(PAM) is applicable when the pH value of the handled water is from neutral to alkaline and the water is a kind of suspension containing more inorganic material. Polyacrylamide Oilfield Chemicals TENORCHEM

The synthesis of gemini surfactants with two different hydrophilic headgroups (cationic-anionic, nonionicnonionic, anionic-nonionic) (Fig. 6b–d) involves more steps. For example, the compound of Fig. 6c was synthesized in three steps: An alkyl dimethyl amine reacts first with ethylbromoacetate and then with hydrazine to give the surfactant

Growth in this field has been especially rapid since 1960; and today, many companies are engaged in synthesis and applications research on polyelectrolytes that are primarily used in four main marketing areas: water treatment, paper, textiles, and oil recovery [l]. Polyacrylamide gel was also used as soil conditioner [2-41.

- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- Does anionic polyacrylamide improve coagulation-flocculation process?

- What spectroscopy is used to identify anionic polyacrylamide flocculant?
- The anionic polyacrylamide (APAM-T) flocculant was characterized by Fourier transform infrared spectroscopy (FTIR), 1 H nuclear magnetic resonance spectroscopy ( 1 H NMR), and scanning electron microscopy (SEM). Furthermore, the X-ray photoelectron spectroscopy (XPS) was conducted to measure the elemental composition.
- What is a polymer flocculant?
- Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
