| Abstract: | A tercopolymer of AM,AA,MA was prepared with K2S2O8 - NaHSO3 as initiatior in water. Theoptimum reaction conditions were monomer distribution 70: 30, initiator of 0.5%, temperatute at 60C and for 4 hours. When the concentration of Ca2+ was 200×10-6 and the addition of copolymer was10×10-6, the efficiency of inhibiting scales of the copolymer is over 90%。 The structure and proper-ties of the tercopolymer prepared were identified by IR and DSC. |
