【Abstract】 A terpolymer was prepared from the monomers of maleic anhydride(MA),2-acrylamino-2-methylpropane sulphonic acid(AMPS) and 2-acrylamino-2-methylpropane phosphonic acid(AMPP).Relations between the polymerization rate and scale inhibition and dispersing effect of the said terpolymer and between the quantity of initiator and proportioning of monomers were studied.Effects of changes of water quality on the inhibition of the terpolymer against the scaling of calcium carbonate were investigated.The inhibition of this terpolymer against the scaling of calcium carbonate was compared with that of other scale inhibitors.The result shows that the said terpolymer has a good polymerization rate and a good inhibition against the scaling of CaCO 3 and Ca 3(PO 4)2,and is a good dispersant for ferric oxide.更多还原
