聚天冬氨酸具有无毒、阻垢效率高、可生物降解等特点，是一种新型的绿色环保型水处理剂。本文在简要回顾阻垢剂合成的基础上，综述了近几年在聚天冬氨酸高分子结构改性方面的研究进展，其改性主要是通过在聚天冬氨酸分子结构上引入一些具有阻垢性能的官能团，如羟基、磺酸基和磷酸基等，改性后的聚天冬氨酸具有更好的性能。最后也对其发展方向进行了分析和展望。
聚天鼕氨痠具有無毒、阻垢效率高、可生物降解等特點，是一種新型的綠色環保型水處理劑。本文在簡要迴顧阻垢劑閤成的基礎上，綜述瞭近幾年在聚天鼕氨痠高分子結構改性方麵的研究進展，其改性主要是通過在聚天鼕氨痠分子結構上引入一些具有阻垢性能的官能糰，如羥基、磺痠基和燐痠基等，改性後的聚天鼕氨痠具有更好的性能。最後也對其髮展方嚮進行瞭分析和展望。
