ABSTRACT:
A process for preparing superabsorbing crosslinked polyaspartate salt by reacting crosslinked polysuccinimide having a weight average molecular weight of at least 20,000 Daltons with neat base or aqueous base wherein the ratio of water to crosslinked polysuccinimide is zero or positive up to about 10, preferably about 3.3. The resulting salt is either a solid or paste.
