| Abstract: | A kind of water soluble scale inhibitor is synthesized based on maleic and acrylic acid and by adding peroxide and sodium hypophosphite.The reaction conditions were optimized as follows:temperature=85～90 ℃,and reaction time=4 hr,the molar ratio of maleic acid to acrylic acid=1∶4,the amount of peroxide=10% and the amount of hypophosphite=20%.When 15×10 -6 of the prepared polymer compound is used for simulated cooling water,static scale inhibiting ratio can reach 96.46% and static corrosion delaying ratio is 14.56%. |

| Keywords: | scale inhibitor from laleic acrylic acid static scale inhibiting rate and static corrosion delaying rate |
