摘要：
以马来酰胺为单体,采用热缩聚法,合成了聚天冬氨酸 (PASP),对其测定了红外谱图和相对分子质量,研究了可生物降解性、阻垢性能及阻垢性能与相对分子质量的关系。研究结果表明,合成的聚天冬氨酸阻垢性能优异,阻垢作用的最佳相对分子质量范围为 2 0 0 0～ 3 0 0 0,是一种可生物降解性好的绿色化学品。

Abstract:
The PASP (polyaspart ic acid)is synthesized by means of pyrocondensation polymerizatio n, using maleamic acid as a monomer.The inf rared spectrogram and molecular weig ht of synthetic products are determined.The biodeg radability, scale inhibition and relation of it w ith molecular are invest ig ated.The results show that PASP is a biodeg radable and excellent green scale inhibito r.The molecular weig ht range is 2 000 ～ 3 000.
