Abstract：A copolymer was prepared from maleic anhydride, 2 acrylamido 2 methylpropane sulphonic acid and 2 acrylamido 2 methylpropane phosphonic acid. The polymerization was initiated by hypophosphite sodium and peroxide in an aqueous solution. Factors effecting on the polymerization rate, the scale inhibiting efficiency and dispersing ferric oxide ability, such as the ratio of monomers, the ratio of initiator, were investigated. Through static and dynamic scale inbibiting experiment, the scale inhibiting effi...

Key words：sulphonate copolymer; scale inhibitor; preparation
