  • Dispersion polymerization of anionic polyacrylamide in an ...

    2017-8-27 · Polyacrylamide (PAM) is an important water-soluble polymer. It can be used as a flocculant for water disposal, strength additives for paper manufacture, oil displacement agents for enhanced oil recovery, and so on (Yan, 1998).At present, anionic polyacrylamide is synthesized mainly by two methods, namely solution polymerization and inverse emulsion/microemulsion polymerization. Solution polymerization has been adopted commonly, but the dissolution process of the dry powder is often tedious. When dissolution of PAM is required, inverse microemulsion/emulsion polymerization is chosen. This uses hydrocarbon as the continuous phase and various surfactants as emulsifi ers. The main advantage of this method is that it can obtain high-molecular weight anionic polyacrylamide and achieve high conversion rates during polymerization, and the anionic polyacrylamide …

  • Final Report on the Safety Assessment of Polyacrylamide

    2021-1-23 · polymers produced from the co-polymerization of the monomer are anionic. These polymerization reactions normally reach 98% completion and can occur in aqueous solutions as well as oil emulsions. In the presence of free radicals, acrylamide is readily polymerized. (41 Polyacrylamide is chemically inert and nontoxic in enzyme carrier systems, but the

  • Cationic polyacrylamide copolymers (PAMs):

    2018-5-18 · Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer’s fate in the soil compartment, the degradation of 14C …

  • A KINETIC ANAYSIS OF THE DEGRADATION OF GRAFTED

    2015-1-30 · Grafted anionic polyacrylamide gel (GAPAMG) finds lots of important applications, like fire extinguishing composition, fillers and reinforcing agent [12]. In the present investigation, GAPAMG was synthesized at the laboratory. The thermal degradation behaviour of GAPAMG is an important parameter for its characterization in various applications.
