Abstract Homopolymer PIA, PSAS, PAMPS and SAS/AMPS/IA terpolymer were synthesized by free radical solution copolymerization using itaconic acid (IA), sodium allyl sulfonate (SAS), 2-acrylamide-2-methylpropionic acid (AMPS) as raw materials. The functional groups of carboxyl group, sulfonate group and amide group were found in the terpolymer by IR and gel permeation chromatography. The static scale inhibition me-thod showed that the scale inhibition effect of homopolymer, blend and SAS/AMPS/IA copolymer with different monomer ratios had significant differences on CaCO₃, and the order of the influence of monomers in the copolymer on scale inhibition effect was IA>AMPS>SAS. The CaCO₃ scale samples were analyzed by SEM and XRD. The CaCO₃ crystals added with PSAS and PAMPS decreased, and the cells showed strip-like texture. The CaCO₃ crystal added with PIA, SAS/AMPS/IA is fragmented, and the edges and corners disappear. The XRD pattern shows that the peak height of calcite is significantly reduced, and the CaCO₃ crystal is gradually transformed from calcite to spherical aragonite. Order of degree of crystal destruction: SAS/AMPS/IA>PIA>PAMPS>PSAS. In the case of adding homopolymer and copolymer separately, the Zeta potential test was performed on the surface of the CaCO₃ crystal. It can be seen from the analysis of electrostatic repulsion energy that carboxyl groups are mainly adsorbed on calcium ions, and the negative charge of sulfonic acid groups increases the potential energy of the scale surface, so the electrostatic repulsion between particles increases, which makes CaCO₃ crystals dispersed stably, and at the same time, the formation of calcite crystals is destroyed. The synergistic effect of the two functional groups makes SAS/AMPS/IA more damage to calcium carbonate crystals. The homopolymer PIA, PSAS, and PAMPS have no synergistic effect among multifunctional groups, so their scale inhibition effect is significantly lo-wer than that of copolymers.
