title: 2-aminopropionitrile polymer. I. The hydrolyzate of the basic fraction.
abstract: The basic fraction of a 2-aminopropionitrile polymer was subjected to acid hydrolysis and was analyzed by means of GC-MS, after trimethylsilylation. The fundamental polymer structural units were alanine, 2,2'-iminodipropionic acid, N-(1-cyanoethyl)alanine, N-ethylalanine, glycine, cyanoglycine, and 5-amino-4-carboxyimidazole residues. The last three units may be derived from hydrogen cyanide. Oligomeric combinations of these units were also detected in the hydrolyzate, due to partial hydrolysis of the polymer.
