Abstract: A novel scale and corrosion inhibitor PMAHP was synthesized by aqueous quadripolymerization using maleic anhydride (MA), acrylic acid (AA), hydroxyethyl acrylate (HEA), and 2phosphonobutane1,2,4tricarboxylic acid (PBTCA) as the raw materials initiated by sodium hypophosphite/sodium persulfate, and the optimal technological conditions were determined. When 20 mg/L of this quadripolymer is used, the scale inhibition rates of CaCO3 and Ca3(PO4)2 are 68.2 % and 90.0 % respectively and corrosion inhibition rate is 56.6 %. The infrared spectrum indicates that PMAHP contains carboxyl, phosphonyl acid groups in its molecular structure.
