摘　　要：以马来酸酐为原料,通过磺化、环氧化和开环聚合等一系列反应合成聚磺酸基环氧琥珀酸(PESSA),合成分子中引入—SO3H基团,通过IR和NMR进行了结构表征,实验表明PESSA具有优良的阻CaCO3、Ca3(PO4)2垢性能及稳定锌盐和分散氧化铁的性能。Polyepoxysulfosuccinic acid has been prepared by using the sulfonation, epoxidation and polymerization procedure of maleic anhydride. -SO3H group is introduced to the synthesized molecule. The polyepoxysulfosuccinic acid is characterized by IR and ^1H, ^13C NMR. Through the scale inhibition test, it has been found that the product has better performance of calcium carbonate and calcium phosphate scale inhibition than usual.
