The structure of poly (β-alanine) polymerized in the solid state was investigated by means of X-ray diffraction and scanning electron microscopy. The reaction was carried out on a single crystal of β-alanine at 170°C for 40h in an evacuated, sealed test tube. The crystal structure of the poly (β-alanine) was assigned to I-type crystal of Nylon 3. The polymer chains were oriented towards the c-axis of the β-alanine monomer crystal. The scanning electron microscopic observations showed that the end view of the etched surface of poly (β-alanine) had mainly fibril-like morphology.
