Abstract:	本實驗以醋酸水溶液溶解幾丁聚醣，分別討論純幾丁聚醣及加入過硫酸鉀裂解劑後之溶液黏度變化與時間、溫度及過硫酸鉀濃度的關係。實驗結果發現，隨著時間增加、溫度越高或過硫酸鉀濃度越大，幾丁聚醣溶液的黏度則越低。結合時間及溫度二因素，可找出下列經驗式：η=k/sub o/e/sup (Ea/RT)/-(a-bT)t，其中E/sub a/為常數，24.8(kJ/mol)。 In this study, chitosan was dissolved in acetic acid solution. The effects of time, temperature and concentration of potassium persulfate (KPS) on viscosity variation of chitosan solution were investigated. Viscosity of chitosan solution was decreased with rising temperature, increasing degradation time or concentration of KPS. Combining the effects of time and temperature, an experimental formula can be found: .eta.=k/sub o/e/sup (Ea/RT)/-(a-bT)t. The value of E/sub a/ is constant, 24.8(kJ/mol).
