Inverse Emulsion Polymerization for the Synthesis of High
Polyacrylamides constitute a class of polymers that can entirely dissolve or swell in water to form a solution or hydrogel, respectively. Free radical polymerization of acrylamide monomer, using both solution and inverse emulsion polymerization, was applied to produce polyacrylamide with various molecular weights. This investigation was focused on the production of polymers with varying
Anionic polyacrylamide(PAM) for water treatment. Anionic polyacrylamide, is a white powder water -soluble polymer with varying molecular weight and charge density. It generate a good flocculation and can decrease the resistance between liquids. It is most often used to increase the viscosity of water (creating a thicker solution) or to

To study the selectivity of polyacrylamide in the selective floc flotation of fine coal, adsorption of anionic polyacrylamide (PAM A401) onto ultra-low ash coal and kaolinite was studied
Dispersions of polyacrylamide particles are formed and treated with a caustic material to hydrolyze the polymer to form anionic acrylamide polymers. A preferred technique for forming these products comprises the formation of a stabilized water-in-oil emulsion of aqueous acrylamide monomer, polymerizing the monomer, reacting the polymer emulsion thus formed with a hydrolysis agent and inverting
Study of polyacrylamide-surfactant system on the water–oil
Study of polyacrylamide-surfactant system on the water–oil interface properties and rheological properties for EOR. Two anionic surfactants (SDS and SLES) and 2-ethylhexanol alcohol as mentioned above as an auxiliary agent were used. An eye-catching micro emulsion was prepared using low concentration of surfactants.

Synthesis, Characterization, and Flocculation Properties
A water soluble branched cationic polyacrylamide (BCPAM) was synthesized using solution polymerization. The polymerization was initiated using potassium diperiodatocuprate, K 5 [Cu(HIO 6 ) 2 ](Cu(III)), initiating the self-condensing vinyl copolymerization of acrylamide and acryloxyethyltrimethyl ammonium chloride (DAC) monomer.

- Can cationic polyacrylamide be used as a dry strength resin?
- Paper having heterogeneous z-directional distribution of a cationic Polyacrylamide (PAM) as a dry strength resin was prepared using an external coating method by which PAM was applied to dried paper.
- How does cationic-type Pam dry-strength resin affect viscoelasticity?
- These findings suggest following things: when cationic-type PAM dry-strength resin was applied by the internal method, the PAM distributes within the fiber wall in a molecularly dispersed state. The induced state of PAM within the fiber wall, with no existence of a phase of PAM, led to the disappearance of the viscoelasticity of the PAM.
- What is a net cationic polyacrylamide dry strength agent?
- Guangyan Wang and Yi Jing* A new net-cationic polyacrylamide dry strength agent was synthesized through free radical polymerization using acrylamide (AM), itaconic acid (IA), N,N-dimethylacrylamide (F), and sodium methallyl sulfonate (T).
- Is polyacrylamide a coagulant or a dispersant?
- This is very much system-dependent. Most solution polyacrylamides fall into the category of coagulants, dispersants, fixatives, and paper strength resins due to the limits of the chemistry, desired active polymer content, desired charge, molecular weights, and shelf-life.
