摘要

Intermediate vector polysuccinimide (PSI) was prepared by polymerization of maleic acid and ammonia at 180°Cin this article. Hydrophilic polyaspartic acid (PASP) derivative was prepared from amino-sulfonic and PSI: Lipophilic PASP derivative was prepared from PSI and diisopropylamine. Their scale inhibition rates of calcium carbonate were evaluated by static scale experiments. The inhibition rate of calcium carbonate was 90.2% when n(amino-sulfonic): n(PSI) =1:14 and the dosage of pharmaceutical was 12mg / L. The inhibition rate of calcium carbonate was 87.6% when n(diisopropylamine):n(PSI)=l:8 and the dosage of pharmaceutical was 15mg /L. The calcium carbonate that collected from static state experiments was analysised by scanning electron microscope (SEM). The results showed that polyaspartic acid derivatives were synthesized which had the best overall performance when n (amino-sulfonic): n (PSI) = 1:14.
