  • Is nonionic polyacrylamide hydrophilic?
  • Nonionic polyacrylamide has a strong hydrophilic character, greater than other nonionic, water-soluble polymers. Despite being described as nonionic synthetic polyacrylamides obtained as a result of polymerization or copolymerization of acrylamides, often contain in their macromolecules about 1–3% of anionic groups .
  • What are the different types of polyacrylamide?
  • Polyacrylamides can be classified into nonionic, anionic, and cationic ones [4, 5]. Each of these types due to their proper-ties is used in many industries, mainly in water treatment, mineral processing, or soil conditioning . Application areas of abovementioned polyacrylamide types depend on the specific function of the polymer needed.
  • What is anionic polyacrylamide?
  • Anionic polyacrylamide is polymer with a large number of negatively charged moieties in the long chains of the PAM macromolecules. It can be obtained by partial hydrolysis of polyacrylamide neutral amide groups, which is shown in (3). This process occurs under moderate temperature by adding sodium hydroxide to the PAM solution [4, 6].
  • Is polyacrylamide ionic or cationic?
  • Polyacrylamide is a water-soluble synthetic polyelectrolyte which consists of repeating units (forming a chain structure and containing hydrophilic groups). Due to the different nature of the groups present in the macromolecules, polyacrylamides can be divided into nonionic, anionic, and cationic ones.
