- What is nonionic polyacrylamide?
- Nonionic polyacrylamide is homopolymer formed of acrylamide, with high purity, good soEubility. high molecular weight. This series of products are with high molecular weight polymer and liner polymer low ion degree. Because of its special groups, and endow it with flocculation and dispersion, thickening and bonding. film. gel. stable colloidal.
- 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 ].
- How to obtain a polyacrylamide with a lower ionic group content?
- In order to obtain a polyacrylamide with a lower ionic group content, factors such as temperature, pH, monomer concentration, and type of polymerization initiator should be manipulated. Nonionic polyacrylamide can be produced from acrylamide monomer by free radical polymerization using various initiation methods.
- 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.
