Polyacrylamide (PAM) China Leading High Molecular Polymer
Polyacrylamide is, simply called PAM, a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields. There are three categories of anionic, cationic and non-ionic type.
Anionic polyacrylamide is of good solubility and can easily dissolved in cold water,samll dosage product can achieve great flocculation.Use it in conjunction with inorganic flocculants can achieve better result.
Solubility of Polyacrylamide in Supercritical Carbon
To promote the application of polyacrylamide (PAM) in carbon dioxide flooding to enhance oil recovery, the solubility of PAM with different molecular weight (5 million, 7 million, 14 million, g·mol–1) was measured using dynamic method in supercritical carbon dioxide (SCCO2) at temperatures of 313, 323, and 333 K and pressures from 9.0 to 18.0 MPa.

Long-Range Correlations in Polymer-Containing Ionic
Ionic liquids containing macromolecules as solutes are of considerable interest for polymer materials science. However, these systems are at an early stage of investigation. In this study, the structural features of ionic liquids containing flexible polymer chains under good solubility conditions are investigated on the basis of the polymer integral equation method.
Product Introduction. Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce friction resistance between liquids, according to ionic characteristics can be divided into non-ionic polyacrylamide, anionic polyacrylamide, cationic polyacrylamide and amphoteric polyacrylamide.
China High Polymer Anionic Polyacrylamide Manufacturers
High purity polyacrylamide product introduction: Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce friction resistance between liquids, according to ionic characteristics can be divided into anionic, cationic, non-ionic and amphoteric.
Three advantages of polyacrylamide: 1.polyacrylamide has the positive gene, flocculation ability is strong, small amount, the treatment effect is obvious. 2.good solubility, high activity, fast settlement, compared to other water-soluble polymer purification capacity of 2-3 times.
Polyacrylamide (PAM) as textile auxiliaries
PAM has strong hygroscopicity, good adsorption and dispersion, good film forming and the smoothness of size, of the fibers with a strong affinity, high strength low elasticity, and all kinds of pulp with good solubility.Adding PAM made from chemical pulp, used for textile sizing, can improve the tackiness, permeability and desizing performance, using PAM pulp processing of fabric can be

Solubility study of polyacrylamide in polar solvents
Contact angles and surface tension data were measured to obtain the surface tension components of polyacrylamide (PAM). According to Van Oss, Chaudhury, and Good (VCG) theory, the surface tension components were used to calculate the PAM solubility in five different polar solvents: water, ethylene glycol (EG), acetone, ethanol, and dimethyl formamide (DMF).
