Polysuccinimide(PSI) was synthesized by pyrocondensation polymerization of L-aspartic acid monomer. Polyaspartic acid containing hydroxyl or sulfo were synthesized from PSI. Scale inhibition and dispersion performance of polyaspartic acid (PASP) and its derivatives were studied. The results showed that the scale inhibition rate on calcium carbonate of polyaspartic acid containing sulfo was 10% higher than that of polyaspartic acid containing hydroxyl. The dispersion performance on Fe2O3 was fine when 15mg/L polyaspartic acid containing sulfo or 30mg/L polyaspartic acid containing hydroxyl were added. Comprehensive performance of polyaspartic acid containing sulfo was better than polyaspartic acid derivatives containing hydroxyl.
