摘要： The invention relates to a method for carrying out polycondensation reactions, according to which the polycondensation of a monomeric starting material is carried out with external supply of heat in a reactor combination which has at least two stages and is composed of a pre-reactor and a high-viscosity reactor, where the low-molecular-weight elimination products produced are removed by evaporation. In the pre-reactor, the reaction product is concentrated to give a high-viscosity preliminary product. The high-viscosity preliminary product is then fed to the high-viscosity reactor, in which it reacts to completion with simultaneous introduction of thermal and mechanical energy and with a residence time of from 20 s to 60 min to give a polycondensation product.

摘要： 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.
