摘　　要：合成了聚环氧琥珀酸(PESA)-β-环糊精(β-CD)-2-丙烯酰胺基-2-甲基丙磺酸(AMPS)三元共聚物,用静态防垢法研究了聚合物的阻碳酸钙垢性能。结果表明:在pH为7、温度为70℃,加入30mg/L的防垢剂时,其防垢率可达92.6%,改性PESA具有良好的防垢性能。XRD和SEM表征结果也表明了改性PESA防垢剂具有能遏制CaCO_3晶体的正常生长的优秀性能。Polyepoxysuccinic acid（PESA）-β-cyclodextrin（β-CD）-2-acrylamido-2-methylpropanesulfonic acid（AMPS）were synthesized and charactered by static Static scale inhibition test.The result showed under the condition of pH=7 and temperature is 70 ℃,the scale inhibition rate reach 92.6%with 30 mg/L modified PESA inhibitor.It result that this modified PESA have great ability to antiscalant.The XRD and SEM photography of CaCO_3 crystal further proof this modified PESA green inhibition have excellent effect to block the process of CaCO_3 crystal growth.
