N2 - Polyglycine and polyalanine obtained by polymerization of their N-carbonic anhydrides often appeared to contain more acid groups than amino groups. This is ascribed, at least partly, to the formation of hydantoin groups. A small amount of 2,5-diketopiperazine was isolated from polyglycine. A discussion of the results and their bearing upon the calculation of molecular weights is given.
