What is nonionic polyacrylamide (NPAM) gel?

Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.

What are Nonhydrolyzed polyacrylamide gels used for?

Nonhydrolyzed, and hence nonionic, polyacrylamide gels are used for electrophoresis media in biotechnology laboratories [72, 73]. Particulate polyacrylamide gels are useful in horticulture . Hydrolysis of polyacrylonitrile can yield first polyacrylamide and eventually some acrylic acid groups.

What is nonionic polyacrylamide?

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM) Structure and Properties: Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain.

What is non ionic polyacrylamide used for?

Non-ionic polyacrylamide, when combined with cellulose, and added with certain chemical additives, is widely used as an oilfield profile control and water blocking agent. It is used as the basic raw material for soil moisturizers and various modified polyacrylamides.

Are crosslinked polyacrylamide gels ionic or Nonhydrolyzed?

Crosslinked polyacrylamides, particularly when partially hydrolyzed to yield acrylic acid moieties, are superabsorbent gels and have been used in selected applications over the years. Nonhydrolyzed, and hence nonionic, polyacrylamide gels are used for electrophoresis media in biotechnology laboratories [72, 73].

Is non ionic polyacrylamide a water soluble polymer?

Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.
