| titleOfInvention | Crosslinked polyaspartate salts and a process for their production |
| abstract | A first embodiment comprises reacting PSI with polyhydrazide selected from the group consisting of dihydrazides and trihydrazides and mixtures thereof, subsequently hydrolyzing the crosslinked PSI with base to produce crosslinked polyaspartate. A second embodiment comprises reacting PSI with hydrazine to form an intermediate product which is reacted with polyacyl chloride or polyester to produce crosslinked PSI followed by hydrolysis to form crosslinked salt. Isolation of the intermediate before reaction with the polyacyl chloride or polyester is unnecessary. |
