amphoteric polymers

The amphoteric polyacrylamide (PAM) produced by our Company under the trade name of LHPAM, is made from acrylic cationic monomer, acrylamide monomer and a hydrolyzing agent through a copolymerization process. Through infra-red sqectrum analysis, it is shown that the molecular chain of the product has not only carboxyl anionic charges resultion from the hydrolysis of acrylamide, but also cationic charges from the acrylic monomer.

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). Basic and acid groups dissociate in an aqueous solution.

Abstract: Amphoteric ionic polyacrylamide P (AM-DAC-AANa) was prepared in aqueous solution using acrylamide (AM), 2-(acryloyloxy) ethyltrimethylammonium chloride (DAC) and sodium acrylate (AANa) as materials by photo assisted initiation. The influences of reaction conditions on intrinsic viscosity and solubility of product were studied.
