以马来酸酐、尿素、二乙烯三胺、1-氨基-2-萘酚-4-磺酸等为原料，合成了聚天冬氨酸/二乙烯三胺（PASP/DETA）和聚天冬氨酸/1-氨基-2-萘酚-4-磺酸接枝共聚物（PASP/1，2，4）；采用红外光谱仪分析了产物的化学结构，并测定了其对工业用水的阻垢性能．结果表明，PASP/DETA对Ca3（PO4）2具有很好的阻垢性能，PASP/1，2，4对CaCO3具有很好的阻垢性能；当二者按PASP/DETA浓度5 mg/L、PASP/1，2，4浓度1．5 mg/L复配使用时，对CaCO3的阻垢率可达95．4％，对Ca3（PO4）2的阻垢率可达95．2％．
以馬來痠酐、尿素、二乙烯三胺、1-氨基-2-萘酚-4-磺痠等為原料，閤成瞭聚天鼕氨痠/二乙烯三胺（PASP/DETA）和聚天鼕氨痠/1-氨基-2-萘酚-4-磺痠接枝共聚物（PASP/1，2，4）；採用紅外光譜儀分析瞭產物的化學結構，併測定瞭其對工業用水的阻垢性能．結果錶明，PASP/DETA對Ca3（PO4）2具有很好的阻垢性能，PASP/1，2，4對CaCO3具有很好的阻垢性能；噹二者按PASP/DETA濃度5 mg/L、PASP/1，2，4濃度1．5 mg/L複配使用時，對CaCO3的阻垢率可達95．4％，對Ca3（PO4）2的阻垢率可達95．2％．

Grafted copolymers polyaspartic acid/diethylenetriamine (denoted as PASP/DETA ) and polyaspartic acid/1-amino-2-naphthol-4-sulfonic acid (denoted as PASP/1 ,2 ,4) were syn-thesized with urea , maleic anhydride , diethylenetriamine and 1-amino-2-naphthol-4-sulfonic acid as the starting materials .The chemical structure of as-synthesized products was analyzed by infrared spectrometry ;and their scale inhibition performance in industrial water was tested . Results show that PASP/DETA possesses excellent scale inhibition performance against Ca3 (PO4 )2 ,and PASP/1 ,2 ,4 possesses excellent scale inhibition performance against CaCO 3 . When PASP/DETA and PASP/1 ,2 ,4 are combined at a concentration of 5 mg/L and 1 .5 mg/L ,they have a scale inhibition efficiency of 95 .4% against CaCO3 and of 95 .2% against Ca3 (PO4 )2 .
