| Abstract: | In this paper, the IPPA/AA/AM copolymer was synthesized by isopropenyl phosphonic acid (IPPA), Acrylic acid (AA) and Acrylamid (AM) with peroxide as initiator and water as solvent. The effects of the concentration of copolymer , Ca 2+ , SO 4 2- , pH value and temperature on inhibiting scale properties of CaSO 4 were investigated. The crystal conformation was observed by scanning electric microscopy . The results show that the copolymer has very good properties of inhibiting scale on CaSO 4. |
