摘　　要：聚环氧琥珀酸(PESA)是一种绿色水处理剂,具有高效的阻CaCO_(3)、CaSO_(4)垢性能,但阻Ca_(3)-(PO_(4))_(2)、分散Fe_(2)O_(3)及缓蚀性能并不突出,在一定程度上限制了其应用范围。通过在PESA分子结构中引入一些具有阻垢性能官能团的化学改性方法或者与其他阻垢缓蚀剂复配的物理改性方法,可以改善PESA的相关性能,扩大应用领域。文章介绍了PESA化学改性和物理改性的研究进展,提出了今后的发展建议。Polyepoxysuccinic acid(PESA)is a green water treatment agent,with high performance of CaCO_(3)and CaSO_(4)scale inhibition,but its performance in Ca_(3)(PO_(4))_(2)and dispersed Fe_(2)O_(3)inhibition,as well as its corrosion inhibition performance are not outstanding,limiting its application scope to a certain extent.By introducing some chemical modification methods of functional groups with scale inhibition properties in PESA molecular structure or physical modification methods with other scale and corrosion inhibitors,the related performance of PESA can be improved so as to improve its application field.The progress of chemical and physical modification of PESA was introduced and suggestions were put forward for its future development.
