Polyelectrolyte polymers¡ªTypes, forms, and function

Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs. The resulting acrylate content (< 3 mol%) does lead to a degree of anionicity with the acrylamide homopolymers manufactured. Again, nonionic polyacrylamide products are available as

Polyacrylamide nonionic water-soluble polymer 9003-05-8

Journal of agricultural and food chemistry, 56 (8), 2773-2779 (2008-03-21) Linear anionic polyacrylamide (PAM) has been used in irrigation practices as a flocculating agent to minimize water losses through seepage in earthen canals. The stability of PAM is of concern because of the possibility of acrylamide (AMD) monomer release during.

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

The Thermal Gelation Behavior and Performance Evaluation of High

The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by varying NPAM or PEI concentration, and a quadratic model is developed by statistical analysis, which predicts the gelation time of NPAM/PEI gel system.

Rheology Properties of Underwater Cement Paste with Nonionic Polyacrylamide

Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2022).The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2.

Molecular Dynamics-Assisted Design of High Temperature-Resistant ... - MDPI

Polyacrylamide has promising applications in a wide variety of fields. However, conventional polyacrylamide is prone to hydrolysis and thermal degradation under high temperature conditions, resulting in a decrease in solution viscosity with increasing temperature, which limits its practical effect. Herein, combining molecular dynamics and practical experiments, we explored a facile and fast

Polyacrylamide Soil Conditioners: The Impact on

Nonionic polyacrylamide has a strong hydrophilic character, greater than other nonionic, water-soluble polymers.
