Characteristics and applications of polyacrylamide - Cpolymer

Polyacrylamide is a water-soluble linear polymer polymerized by acrylamide (AM) monomer initiated by free radicals. It has good flocculation and can reduce the frictional resistance between liquids. It can be divided into ionic characteristics. There are four types of non-ionic, anionic, cationic and amphoteric type.

experimental and theoretical study of dilute polyacrylamide

Experimental and theoretical study of dilute polyacrylamide

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 radius gyration and the hydrodynamic radius (¦Ñ) were

Extensional rheology of hydrophobically associating

Partially hydrolyzed polyacrylamide (HPAM) and hydrophobically associating polyacrylamide (HAHPAM) were supplied by the Hengju Chemical Group Co., Ltd., China. The molecular weights of HPAM and HAHPAM were 2.2 ¡Á 10 7 and 1.3 ¡Á 10 7 g?mol ?1, and their degrees of hydrolysis were 24.9% and 21.5%, respectively.

Pore-Scale Flow Fields of the Viscosity-Lost Partially

The rheology of a partially hydrolyzed polyacrylamide (HPAM) solution plays an important role in its oil recovery during polymer flooding. However, multiple factors in brine, such as sulfide ions, cause a dramatic loss in the viscosity and oil recovery.
