摘要: This investigation determined a feasible route to prepare hyperbranched polyesters involving citric acid (CA) and glycerol (GLC) monomers (CA-co-GLC) using thermal polycondensation method. The synthesized copolymer was characterized Fourier transform infrared spectroscopy (FT-IR), carbon-13 nuclear magnetic resonance spectroscopy, differential scanning calorimetry. ability of CA-co-GLC inhibit deposition inorganic scales such as calcium carbonate investigated under varying temperature pH medium. evaluation inhibition efficiency (IE) conducted the static scale mechanism inhibitor’s action via growth solution analysis, measurement conductivity, analysis CaCO3 FT-IR electron microscopy. results obtained showed that had good IE at an elevated reaching 75% 100 °C, 7.5, 10 ppm dose. Using same dose, reached 66% 50 °C 10. did not chelate Ca2+ in water, but led change polymorphism, making it brittle able slip easily from surface. Its principally prevented adhesion onto
