摘要

利用L-天冬氨酸热缩聚合,磷酸作催化剂条件下的L-天冬氨酸热聚合以及马来酸、氨水为原料热聚合等三种方法,合成了可生物降解的绿色高分子聚天冬氨酸(PASP),所得产物相对分子质量在1800~5000之间,用静态阻垢法研究比较了以上三类产物的阻垢性能,结果表明:PASP具有优良的阻CaCO₃、CaSO₄和BaSO₄垢的性能,其中相对分子质量<2000的聚天冬氨酸对碳酸钙和硫酸钡的阻垢性能较差,但对硫酸钙的阻垢效果相对较好。

Abstract

Polyaspartic acid is synthesized by three methods,the thermal pol ycondensation of L-aspartic acid,acid-catalyzed polycondensation of L-aspar tic acid and polycondensation of maleic acid with ammonia.The molecular weight of PASP synthesized by these methods is 2 500, 5 000 and 1 800 respectively.The scale inhibition properties of the above PASP products are studied.The results show that all the three kinds of PASP have a good scale inhibition effect on CaCO₃, CaSO_{4_{and BaSO_{4_{.It also indicates that the product with lower molecular we ight of 1 800 has a comparably inferior scale inhibition on CaCO₃ and BaSO₄ than CaSO₄}}}}

Key words： polyaspartic acid; synthesis; scale inhibition
