Polyacrylamide degradation and its implications in environmental

Acrylamide at a dose of 20 mg/kg/day stimulated the degeneration of peripheral nerves and the spinal cord of rats, although no obvious effects were found at doses less than 0.2 mg/kg/day. 152

Experimental study and application of gels formed by nonionic

Nonionic polyacrylamide (NPAM) and phenolic resin cross-linker were purchased from Yuguang Co. Ltd., China. The hydrolysis degree and average molecular weight of NPAM were 3.31% and 9,650,000 g/mol, respectively. The low salinity of brine (492.08 mg/L) was used in all experiments. Preparation of gels

Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization. The effects of the monomer concentration, initiator concentration, reaction time, feeding temperature and reaction temperature on the molecular weight were systematically investigated through single-factor and orthogonal experiments.

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

Abstract A delayed crosslinked polymer gel was developed for in-depth water control in mature oilfields. 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 role of hydration degree of cations and anions on the adsorption

A colloidal force probe was employed to characterise the adsorption of high-molecular-weight, nonionic polyacrylamide on glass surfaces at a pH of about 6.5 and 22 ¡ãC. Three 0.27 M salts (LiCl, KCl, and KNO 3 ) were used to investigate the effect of different cations (Li + , K + ) and anions (Cl ? , NO 3 ? ) on the polymer adsorption kinetics.
