Abstract

Through a solution polymerization method,barium sulfate scale inhibitor MMS was synthesized under the following optimum conditions: monomer ratio of n(MA)∶n(MAA)∶n(SAS)=1∶0.8∶0.1,initiator dosage of 1%,20.48% monomer concentration,pH=2,reaction temperature 80 ℃,and reaction time 5 h.Under different conditions,the performance of the scale inhibitors was evaluated,and the anti-scaling rates were found up to 99%.According to the features of the molecular structure of MMS,the barium sulfate scale inhibiting mechanism was studied.
