Abstract

Polysuccinimide is produced by thermal polymerization of a precursor or a reactant admixture that includes an unsaturated compound in a plate-type reactor (14) at temperatures sufficient to initiate polymerization and to form a brittle solid.
The so-obtained polysuccinimide can be hydrolyzed to polyaspartic acid or to a polyaspartic acid salt, if desired. The precursor can be a monomer or a mixture of reactants that form polymerizable intermediates.
