摘要：
A method of manufacturing a new N-carboxyamino acid anhydride and polyamino acid using a simple process operation. The method for manufacturing N-carboxyamino acid anhydride comprising reacting &agr;-amino acid with di-tert-butyltricarbonate. The method for manufacturing polyamino acid comprising decarboxylating the N-carboxyamino acid anhydride obtained by reacting &agr;-amino acid with di-tert-butyltricarbonate.
