摘要: A novel quadripolymer scale inhibitor poly-maleic anhydride-acrylic acid-acrylamide-sodium
methallyl sulfonate (PMAAS) was synthesized by solution polymerization with maleic
anhydride (MA), acrylic acid (AA), acrylamide (AM), sodium methallyl sulfonate (SMAS), etc.
IR spectrum shows that PMAAS contains carbonyl, hydroxyl, phosphatic and sulfonic acid
group. SEM indicates that PMAAS blocks the normal growth of scale CaCO3 and CaSO4 crystals.
The influences of PMAAS concentration, Ca2+ concentration, temperature and pH value of the
system on the inhibition efficiency are investigated. The inhibition efficiency of PMAAS is
superior to com-mercial inhibitors T-225 and XF-192.
