EFFECT OF HYDROPHOBIC ASSOCIATION ON STRUCTURE AND RHEOLOGICAL BEHAVIORS OF POLYACRYLAMIDE BASED AQUEOUS SOLUTIONS

Partial hydrolyzed polyacrylamide(HPAM) and associating partial hydrolyzed polyacrylamide(AHPAM) were compared focusing on the structure and rheology relations,which play important roles in enhanced oil recovery.The molecular associating state in AHPAM aqueous solutions is studied in terms of molecu...
