Abstract
A novel modified polyepoxysuccinic acid polymer, epoxysuccinic acid-oxalic acid-allypolyethoxy carboxylate (ESA-co-APEM, PEM), was prepared through free-radical polymerization reaction of ESA and APEM and characterized by Fourier transform infrared spectroscopy. The polymer's ability to inhibit calcium sulfate scale formation, disperse ferric oxide is investigated by static tests and its corrosion inhibition performance was studied via weight loss measurements. The scale inhibition efficiency of CaSO4 could reach 99% in the concentration of 4 mg/L, the best dispersion efficiency was reached to 20% (transmittance) when 18 mg/L of PEM was used, and the corrosion inhibition efficiency increased to 70% when the concentration was 60 mg/L. Scanning electron microscopy was used to analyze the effects of PEM on morphology of calcium sulfate and corrosion inhibition of carbon steel. The results showed that PEM possessed outstanding ability of inhibition, dispersion and corrosion inhibition properties.This publication has 17 references indexed in Scilit:
