polyacrylamide is a solid powdered water-soluble polymer with different molecular weights and charge densities. It is most commonly used to increase the viscosity of water or promote flocculation of particles in water and make fine suspended solids settle quickly.

macromol free full-text current research on,polyelectrolytes have been at the center of interdisciplinary research for many decades. in the field of polymer science and soft matter, they have provided the dimensions of electrostatic interactions, which opens a vast variety of opportunities for new physical properties and applications. in biological matter, polyelectrolytes are present in many forms, from extracellular polysaccharides to

Is acrylamide a copolymer?
Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other species, such as an acrylic acid or a salt thereof. These copolymers have modified wetting and swellability.
Is polyacrylamide a powder or liquid?
Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other species, such as an acrylic acid or a salt thereof.
What is the standard state of polyacrylamide?
Unless otherwise stated, data refer to materials under standard conditions (25 °C [77 °F], 100 kPa). Polyacrylamide (abbreviated PAM or pAAM) is a polymer with the molecular formula (-CH 2 CHCONH 2 -).
Is polyacrylamide contaminated with acrylamide?
Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide.
