A terpolymer scale inhibitor called IA/IBS/AA is prepared from IA (itaconic acid),IBS (isobutylene sulfuric acid)and AA(acrylic acid)in water phase. The optimum conditions of the synthesis of IA / IBS /AA terpolymer are determined as follows:the monomer mass ratio m(IA)∶m(IBS)∶m(AA)= 10 ∶3 ∶5,the initiator 6% (wt. of total monomers),the chain- transfer agent 9%(wt.of total monomers),the reaction temperature 95 ℃,the reaction time 1.5 h. The efficiency of inhibiting CaCO3 scales of the terpolymer is 94.65%,and the terpolymer can be used as scale innibitor in cooling water for industrial circulating water. The synthesis of terpolymer is applied to factories and shows a good effects.
