What is the ionicity of anionic polyacrylamide?

Ionicity ranges from 5%~60%. UPSCHEM Anionic Polyacrylamide is widely used as Drilling Fluids Additives, Friction Reducer in Oilfield, and used as Flocculant in Water Treatment and Mining Industries.Anionic Polyacrylamide could be supplied in solid powder and emulsion forms.

What determines the molecular weight of anionic polyacrylamide?

The molecular weight is determined by the type and concentration of the reaction initiator and the reaction parameters. Anionic polyacrylamide has no systemic toxicity to aquatic organisms or micro-organisms. The polymer is much too large to be absorbed into tissues and cells.

What are the different types of anionic polyacrylamide synthesis technologies?

The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.

Is anionic polyacrylamide toxic?

Anionic polyacrylamide has no systemic toxicity to aquatic organisms or micro-organisms. The polymer is much too large to be absorbed into tissues and cells. The functional anionic groups do not interfere with the functioning of fish gills or daphnia respirators.

What is cationic polyacrylamide?

Cationic polyacrylamide, is a white powder water -soluble polymer which is copolymerized by cationic monomer and acrylamide. It has the function of decolorizing, adsorbing, turbid eliminating and bonding. It generate a good flocculation and can decrease the resistance between liquids.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (APAM) is a kind of polyacrylamide (PAM) and shows electronegative which contains functional groups of sulfonic acid, phosphoric acid or carboxylic acid .
