Versuchsvorschrift

FIG. 9. Infrared spectrum of the 2:1 copolymer of monosodium aspartate and succinimide, produced via thermal polymerization of monosodium aspartate and monoammonium aspartate at 200° C. for 3 hours. The amide peaks in the region of 1600 cm−1 became more prominent with increasing relative amounts of monosodium aspartate monomer. The imide peak at ˜1716 cm−1 tended to become accentuated with longer reaction times, as aspartic acid residues were driven more toward the succinimide form. Again, the carboxylate peak at ˜1400 cm−1 is prominent and the monomeric peaks in the fingerprint region (<1000 cm−1) are absent.
