Polymerization of perhydro‐1,5‐diazocine‐2,6‐dione

Abstract

Abstract Perhydro‐1,5‐diazocine‐2,6‐dione polymerized in solid state in the presence of water in vapor phase and produced poly‐β‐alanine almost quantitative yield. Further, this monomer was found to polymerize rapidly on heating above its melting temperature without water. The results of x‐ray diffraction measurement and thermal analysis suggest that this solid‐state polymerization is like partial melt polycondensation.
