摘　　要：Polyaspartic acid(PASP) was prepared by hydrolysis of the polysuccinimide, which was mechanochemically synthesized from maleic anhydride and ammonium hydroxide in nitrogen atmosphere protection. The scale and corrosion inhibitions of PASP was evaluated and compared with 2-phosphonobutane-1,2,4-tricar- boxylic acid(PBTCA), 1-hydroxyethylidene-1,1-diphosphonic acid(HEDP) and hydrolyzed polymaleic anhydride(HPMA). The results revealed that the inhibition of the PASP is close to that of PBTCA and HEDP, but much better than that of HPMA.
