摘　　要：以马来酸酐为原料制备聚天冬氨酸,并对聚合反应的质量配比、聚合温度和聚合时间三个反应条件进行了优化实验,对最优条件下合成的PASP与其它阻垢剂进行了性能对比。结果表明:合成PASP的最佳条件是:原料质量配比为1∶1.1,聚合温度为160℃,聚合时间为1h,阻垢率可以达到95%以上,生物降解性能达到70%。Polyaspartic acid （PASP） was prepared by the means of polymerizing maleic anhydride and ammonia solution. In order to find optimal condition of synthesizing PASP, we made a set of experiments on proportion of material, temperature and time of polymeri- zation in the single condition, and compared PASP with other scale inhibitors about the performance of scale inhibition and biodegradation . The results show ： the optimal proportion of material is 1 ： 1.1, the temperature of polymerization is 160℃, and the time of polymerization is l h. Under above condition, we synthetized the PASP its inhibiting efficiency can reach over 95%, and biodegradation rate reaches 70%.
