Abstract: Improving the biodegradability of organic corrosion&scale inhibitor,and synthetizing environment-friendly corrosion and scale inhibitor is of important significance to the protection of ecology. The low phosphonic maleic an-hydride-urea terpolymer MA-SHP-UREA (PMASU) has been synthesized by using sodium hypophosphite (SHP), maleic anhydride(MA),and urea(UREA) as raw materials,water as solvent,H2O2 as initiator,and metallic salts as catalysts. The molecular structure of PMASU is characterized by UV spectra and IR spectra. The optimum conditions for the synthesis of PMASU,its corrosion and scale inhibiting capacity and biodegradability are discussed. When the mass concentration of this copolymer is 10 mg/L ,its scale inhibiting rate is higher than 92%,corrosion inhibiting rate reaches 81.3%,and has very good biodegradability.
