Properties and Applications of Polyacrylamide (PAM)
To solve the above problems, in this work, we report a facile and efficient one-pot and one-step aqueous Cu (0)-mediated RDRP strategy for well-controlled AM polymerization. Through this new approach, the well-controlled polymerizations of AM have been successfully achieved with well-defined PAM structure and a range of Mw s.

Get PriceWhat is polyacrylamide (PAM)?
This chapter discusses polyacrylamides (PAM). Among the various polymers that have been studied for chemical enhanced oil recovery, PAM is most important. PAM is used frequently for mobility control as well as permeability control. PAM (and its modified forms) is the principal polymer used in significant amounts on a commercial basis.
What are the different types of anionic polyacrylamide synthesis technologies?
The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
Which polymer is made by polymerization of acrylamide monomer?
PAM is made by the polymerization of acrylamide monomer, whereas PAM/AA is manufactured either by copolymerizing acrylic acid or via hydrolysis of the homopolymer. Polyacrylamide is a water-soluble polymer that undergoes reactions typical of the amide group.
What is polyacrylamide used for?
Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.
How to control acrylamide polymerization?
To conclude, the controlled polymerizations of acrylamide have been successfully achieved via a one-pot and one-step aqueous Cu (0)-mediated RDRP approach. It has been demonstrated that strong deactivation control is the key for the control in AM RDRPs.
What is the difference between acrylamide monomer (AMD) & AA (Pam/AA)?
PAM is made by the polymerization of acrylamide monomer, whereas PAM/AA is manufactured either by copolymerizing acrylic acid or via hydrolysis of the homopolymer. The structures for acrylamide monomer (AMD), PAM, and PAM/AA are shown in Fig. 8-1.
