| Abstract: | The degradation rates of poly ( butylenes succinate) (PBS) films were compared in aqueous solution with different pH values. The experimental results were characterized by weight loss rate and the observation of surface morphology. The results indicated that the degradation rates of PBS films in aqueous solution on different pH values reduced as follows; alkaline solution > acidic solution > neutral solution. The pH values of various degradation aqueous solutions decreased in different degrees. |
