Abstract:

It is noteworthy that the hydrophobically associating acrylamide copolymer is a new class of water-soluble polymers, derived from polyacrylamide by introducing a relatively low amount of hydrophobic groups(generally less than 5%, molar fraction) in polymer hydrophilic macromolecule chains. Because of special pro-perties of temperature resistance, salt tolerance, resistance to shear and storage stability, the material has been widely used in industry. The water-soluble negatively charged polyacrylamide was prepared by free radical copolymerization method. The interaction between cationic surfactants and polyacrylamide was researched in aqueous solution and NaCl solution including solubility, viscosity and rheological properties.

Key words: Polyacrylamide, Cationic surfactant, Oil displacement
