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. [1] Physicochemical properties [ edit]

rheology properties of underwater cement paste with nonionic polyacrylamide

Rheology Properties of Underwater Cement Paste with Nonionic Polyacrylamide

Abstract In this article, underwater cement paste (UWP) was fabricated through using the high molecular nonionic polyacrylamide (PAM) as anti-washout admixtures (AWAs). The traditional coaxial rotary method was used to systematically investigate UWPs rheology parameters.

biodegradation of polyacrylamide and its derivatives

Biodegradation of Polyacrylamide and Its Derivatives

Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 ¡Á 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).

Simultaneous thermal analysis of cationic, nonionic and anionic

In contrast simultaneous thermal analysis can be applied to determine the effective PAM content in smectite-PAM composites. At the same time, information on the thermal stability of PAM and of smectite-PAM composites are available. Tutas et al. (1987) studied the decomposition of polyacrylamide (PAM) up to 600 ¡ãC under N 2 using simultaneous

2.4. Nonionic PAM Nonionic PAM was a anionic polyacrylamide with hydrolysis degree of less than 5%. Due to the existence of a certain number of polar groups in its molecular chain, it can be a bridge among the suspended solid particles in water to combine the particles or agglomerate the particles to form large flocs by neutralization.

polyacrylamide soil conditioners: the impact on

Polyacrylamide Soil Conditioners: The Impact on

The polymer adsorption increases with the following order: anionic PAM < nonionic PAM < cationic PAM . Nonionic polyacrylamide adsorption on clay minerals is mainly caused by van der Waals forces [ 80 ], whereas cationic or anionic forms adsorb and bind soil particles through electrostatic forces or bridge formation between PAM charged moieties and solid surface group [ 1 , 80 ].
