Experiment 2: Characterization of polyacrylamide (PAM) by
Aim: (a) To determine the intrinsic viscosity and molecular weight of polyacrylamide (synthesized in experiment 1) using a Ubbelohde capillary viscometer. (b) To measure the shear rate dependent viscosity of "concentrated" PAM solutions by using a coaxial cylinder (Couette) viscometer.

Polyacrylamide Handbook - SNF
polyacrylamide emulsions and powders Handling of emulsions using pumps is simpler than powders and in many cases, in-line injection can be used, avoiding the need for an aging tank. Furthermore, dissolution times are much shorter and there are almost no solubility problems. Unlike powders, emulsions are complex multicomponent products which include

How to Control Polyacrylamide Viscosity - Sinofloc Chemical
The viscosity of the anionic polyacrylamide solution decreases with increasing temperature due to the fact that the dispersed phase particles of the polymer solution are entangled with each other to form a polymer of a network structure. When the temperature is higher, the network structure is more easily destroyed, and the viscosity will decline.

How to Control Polyacrylamide Viscosity – Sinofloc Chemical . Pure polyacrylamide is easy to hydrolyze. In the aqueous solution, when the PH value from acid to alkaline range, the non-ionic amide to anionic carboxyl, carboxyl negatively charged and produce repulsion, resulting in macromolecule stiffness, increasing the friction between molecules, viscosity and thus significantly to increase

Experimental and theoretical study of dilute polyacrylamide
Abstract. The structure and intrinsic viscosity of the partially hydrolyzed polyacrylamide (HAPM) and polyacrylamide (PAM) in aqueous solution were investigated by comparative studies of molecular dynamics simulation over a wide range of the NaCl concentration. The radius of gyration (R (g)), the hydrodynamic radius (R (h)) and the ratio of the

Review on chemical enhanced oil recovery using polymer
The swelling ratio of the gels increased with the concentration of sodium alginate at a constant temperature, and decreased with an increase in temperature. The use of sodium alginate in semi-IPN structures also improved the mechanical strength and the cumulative release of BSA from the gels, indicating potential in drug delivery applications .
