以水为溶剂,次亚磷酸钠 -过硫酸钠为引发剂,丙烯酸 (AA)和 2-丙烯酰氨基 - 2 -甲基丙磺酸(AMPS)为单体合成了集膦酸基、羧酸基和磺酸基于一体的共聚物。考察了该共聚物阻垢性能与单体配比、引发剂用量、反应温度和反应时间等之间的关系。研究结果表明,该共聚物具有较好的阻CaCO₃ 垢、阻Ca₃ (PO₄)₂垢和抑制锌盐沉积的能力。

The copolymer is prepared from the monomers of acrylic acid (AA)and 2-acrylamido -2-methyl- propanesulfonic acid (AMPS)in water solvent, initiated by sodium hypophosphite-sodium persulfate initiators. It contains phosphonic acid, carboxylic acid and sulphonic acid groups.The effects of the monomer' s ratio, the amount of initiator, reaction temperature and reaction time on the corresponding product' s scale inhibiting performance have been studied.The results show that the copolymer possesses quite good effect on reducing scale depositions of CaCO₃, Ca₃(PO₄)₂and zinc salts.
