Polyelectrolyte polymers¡ªTypes, forms, and function

Polymer polyelectrolytes can be prepared and are available as aqueous solutions, liquids (inverse emulsions and aqueous dispersions), and in dry solid forms (powders and beads) depending on the chemistry and the needs of the application.

Difference and application of cationic, anionic and nonionic PAM

Nonionic polyacrylamide (NPAM): it is a kind of high molecular polymer or polyelectrolyte. Its molecular chain contains a certain amount of polar genes, which can adsorb the suspended solid particles in water and bridge the particles to form a large flocculate.

Polyacrylamide Soil Conditioners: The Impact on

Polyacrylamides (PAMs) are group of water-soluble, synthetic polyelectrolytes derived from acrylamide monomer in polymerization process [ 1, 2, 3 ]. They are substances which dissolve, disperse, or swell in water and thus can modify physical properties of aqueous system due to thickening, gelation, emulsification, or stabilization processes.

Polyelectrolytes, Properties

The presence of charged groups leads to several important differences in solution behavior of polyelectrolytes, compared to uncharged polymers : (i) the crossover concentration from dilute to semidilute is much lower; (ii) a pronounced peak (whose wave-vector magnitude increases with c 1/2) appears in the scattering function of homogeneous polyelectrolyte solutions, not in that of nonionic

Polyelectrolyte

Charge Acids are classified as either weak or strong (and bases similarly may be either weak or strong ). Similarly, polyelectrolytes can be divided into "weak" and "strong" types. A "strong" polyelectrolyte is one that dissociates completely in solution for most reasonable pH values.

PAM is often used in traditional coagulation processes as a coagulant-aid (Cirtiu et al., 2011; Liu et al., 2016; Wang et al., 2015). So three types of PAM were selected as modification agents, including anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM), and nonionic polyacrylamide (NPAM), which had different electrical properties.

A polymer electrolyte was developed by blending lithium (LiPAA) with non-ionic polyacrylamide (PAM). The LiPAA-PAM showed synergic effect and achieved an ionic conductivity of 13.8 ¡À 2.4 mS cm ?1, higher than previously developed neutral pH polymer electrolytes. Chemical and structural characterizations of the LiPAA-PAM films revealed a

PAMPS, as a typical anionic polyelectrolyte with sodion as contra-ion, exhibits much large swelling ratio of ¡«10. Note that PAA, PAM and PMAA hydrogels show lower swelling ratio than that of PAMPS hydrogel, and the superabsorbent capacity comes from the strong intrinsic polyelectrolyte macromolecules.
