绿色生物高分子聚天冬氨酸的合成及其阻垢性能研究

摘要

The PASP (polyaspartic acid) is synthesized by means ofpyrocondensation polymerization, using maleamic acid as a monomer. The infrared spectrogram and molecular weight of synthetic products are determined. The biodegradability, scale inhibition and relation of it with molecular are investigated. The results show that PASP is a biodegradable and excellent green scale inhibitor. The molecular weight range is 2 000～3 000.%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2000～3000，是一种可生物降解性好的绿色化学品。
