| Abstract: | Poly (anhydroaspartic acid) was prepared by thermal condensation of L-aspartic acid, which can be hydrolyzed to poly. The weight-average molecular weights (Mw) were measured with GPC. Poly was characterized with the method of NMR. It was demonstrated that poly was a good fertilizer synergist. |
