摘　　要：根据采用原料的不同总结了制备聚天冬氨酸 (polyasparticacid ,以下简称PASP)的不同路线及方法 ,介绍了PASP的结构和降解性能以及其阻垢性能和相对分子质量之间的关系。并且从微观角度阐述了PASP与水形沉积物碳酸钙、磷酸钙和硫酸钡之间的作用情况 ,从而解释了PASP对三种矿物质在水溶液中成核及结垢过程中的影响行为。This review introduces briefly the synthesis of polyaspartic acid(PASP) according to the different original materials.The relationship of the structure of PASP,it's biodegradability and the average molecular weights has been studied. Besides, the interaction mechanism between PASP and scale, such as calcium carbonate, calcium phosphate and barium sulfate from the view of microcosmic point, as well as the effect of PASP in aqueous solution on the nucleation and the growth of these three kinds of mineral have been discussed. In addition, some aspects remain to be investigated further.
