Polysuccinimide and polyaspartic acid are prepared by polymerizing maleic anhydride, ammonia and water or maleic acid derivatives or fumaric acid derivatives in bulk or dissolved in solvents in a continuous kneading reactor. The polysuccinimide formed can be converted into polyaspartic acid and polyaspartate salts by hydrolysis.
