Biodegradability of poly (ε-caprolactone-<i>co</i>-ε-caprolactam) s and poly (ε-caprolactone-<i>co</i>-ω-laurolactam)s was evaluated by enzymatic hydrolysis test, activated sludge test and sea-water test. The enzymes used for hydrolysis test were lipases from Rhizopus arrhizus, Rhizopus delemar, Candida cylindracea and Pseudomonas Fluorecence. The activated sludge test was conducted mainly by a modified ASTM (American Society for Testing and Materials) method. The biodegradability was evaluated with the amount of evoluved CO<sub>2</sub>. The results were similar to those by JIS (Japanese Industrial Standard) method based on BOD (Biochemical Oxygen Demand). The sea-water test carried out in a marine environment, at Kushimoto bay. Most of copolyesteramides were completely degraded for 3 months. The poly (ε-caprolactone-<i>co</i>-ε-caprolactam)s were degraded by the enzymatic hydrolysis test, the activated sludge test and the sea-water test. On the contrary, the poly (ε-caprolactone-<i>co</i>-ω-laurolactam)s were degraded by activated sludge test and sea-water test, however the enzymatic hydrolysis test showed negative results.
