Abstract

The mixture of α-aminopropionitrile and α,α′-iminodipropionitrile polymerized to solidify almost at the temperature near 0°C during 8 years. The conversions based on decreasing of those reactants were 61 and 98% at 4 and 8 years, respectively. The fractionation of 4 and 8 years product using Sephadex G 10 yielded their predominant amounts in the oligomer and polymer section, respectively. The oligomer section product of 8 years product was analyzed by means of ion exchange chromatography and its trimethylsilyl derivative was also analyzed by means of gas chromatography combined with mass spectrometry. These results identified dialanine and trialanine and their amides and nitriles.
