Preparation and properties of amphoteric polyacrylamide

Amphoteric polyacrylamide (AmPAM) has been widely used in the wet-end of the papermaking process as a strength additive because of its unique features. AmPAM is a typical polyampholyte, carrying both basic and acid groups along the molecular chain (Dobrynin et al. 2004).

Amphoteric Polymer & Polyacrylamide Flocculants（PAM）- Sinofloc

Amphoteric polyacrylamide is copolymerized by acrylic cationic monomer and acrylamide monomer. The anionic charge forms after the hydratization of the acrylamide monomer, and the cationic charge forms from the acrylic monomer. Thus, the amphoteric polyacrylamide has both positive and negative charges on its molecular chain.

Revealing Adsorption Behaviors of Amphoteric Polyacrylamide

1. Introduction. Amphoteric polyacrylamide (AmPAM) is a typical polyampholyte, carrying both basic groups and acid groups along the molecular backbone chain [].Due to the unique structure and properties, AmPAM has been used in a broad range of applications involving wetting, lubrication, adhesion, colloidal stability control, drug delivery and gene therapy, and paper strength improvement [2,3

Preparation and properties of amphoteric polyacrylamide

The particle size of the synthesized amphoteric polyacrylamide (AmPAM) ranged from 1 to 8 μm and the intrinsic viscosity ranged from 5.6 to 14.2 dL/g. The influences of aqueous solution of AS concentration, stabilizer concentration, initiator concentration, monomer concentration on the conversion of monomer, the intrinsic viscosity, and the

(PDF) Preparation of novel amphoteric polyacrylamide and its

Furthermore, it was clear that the diameter of amphoteric polyacrylamide particles increased from 322 to 2886 nm in saline. There are two main reasons: (i) the copolymers could be easily precipitated from saline solution due to the salting-out effect; (ii) increasing salt concentration induced the shrink of the stabilizer molecules, resulting
