摘要：
合成了含羟基的聚天冬氨酸衍生物，研究了聚天冬氨酸衍生物及其复配物阻CaCO3、CaSO4和Ca3（PO4)2垢性能，并与聚天冬氨酸和2-膦酰基丁烷-1，2，4-三羧酸水处理剂作了比较，结果表明，质量浓度为12mg/L时，以上4种药剂阻CaCO3垢率分别为11.1%、86.2%、65.7%、94.8%；阻Ca3（PO4)2垢率分别为100%、95.6%、6.47%、7.23%；阻CaSO4垢率分别为94.1%、99.5%、100%、44.3%。复配物对CaCO3、CaSO4和Ca3（PO4)2具有良好的阻垢性能。

Abstract:
Polyaspartic acid(PASP)derivatives with hydroxyl has been synthesized. The performance of it and its combinations have been studied and compared with other water treatment agents such as PASP and 2-phosphono-butane-1,2,4-tricarboxylic acid(PBTCA). The results show that at a dosage of 12mg/L, the inhibition rates of these agents on the precipitation of CaCO3 are 11.1%, 86.2%, 65.7%, 94.8%; and on precipitation of Ca3(PO4)2 are 100%, 95.6%, 6.47%, 7.23%; and on precipitation of CaSO4 are 94.1%, 99.5%, 100%, 44.3% respectively. Its combinations has excellent scale inhibition to CaCO3, CaSO4 and Ca3(PO4)2.
