• It has been found that, when the polymerization of NCA is initiated with <I>n</I>-butylamine in acetonitrile, the amino end group in the polymer produced which is insoluble in the solvent is active (Y. Iwakura, K. Uno and M. Oya, <I>J. Polym. Sci., Part A-1</I>, <B>8</B>, 2165 (1968)). The amino end group in the polymer isolated without drying could initiate the polymerization of NCA in acetonitrile. By using this characteristic of the polymer, block copolypeptides consisting of various kinds of α-amino acid and of various chain lengths were synthesized. The solubility of the block copolypeptides in a solvent was different from that of the random copolypeptides obtained by the usual copolymerization of a mixture of NCA in acetonitrile. Sometimes the infrared spectra of the block copolypeptides were different from those of the random copolypeptides.
