Versuchsvorschrift

The IR spectrum of the product obtained after heating at 180° C. for three hours showed the peaks associated with polymers of aspartate, e.g. at 1391 (carboxylate), 1533 and 1589 (primary amide doublet), and 3300 cm−1 (carboxylate), as well as signals characteristic of asparagine residues, at 1648 cm−1 and 3072 cm−1 (side chain of the —CONH2 R-group) (3300 s, 3072 m, 1648 s, 1589 s, 1533 s, 1391 s, 1196 w). After heating at 220° C. for 4.5 hours, the imide signal at 1704 cm−1 began to emerge, as a result of ammonium aspartate residues being converted to succinimides (3292 s, 3057 w, 2933 w, 1704 sh, 1651 s, 1585 s, 1392 m, 1290 w, 1197 w). After heating at 220° C. for 10 hours, the imide signal at 1704 cm−1 became prominent (FIG. 6) (3300 s, 1704 s, 1664 m, 1530 s, 1383 m, 1355 m, 1296 w, 1194 m).
