摘　　要：综述了近年来国内外废聚β-羟基丁酸酯(PHB)材料化学解聚的研究现状,重点介绍的主要化学解聚工艺方法包括热裂解法、水解法和醇解法等。其中水解法包括高温高压水解、酸性水解和碱性水解及酶催化水解;醇解法包括甲醇醇解和乙二醇醇解等。并对废聚β-羟基丁酸酯在离子液体介质中进行化学解聚行为的可行性进行了探讨和展望。The research progresses in chemical depolymerization of waste poly（β-hydroxuutyrate） （PttB） at home and abroad in recent years were reviewed. In this paper,the main chemical depolymerization methods including pyrolysis, hudrolysis and alcoholysis were introduced. Hydrolysis methods included high temperature and high pressure hydrolysis, acidic hydrolysis and alkaliline hydrolysis. Alcoholysis methods included methanolysis,glycolysis,and so on. The feasibility of chemical depolymerization of waste PHB in presence of ionic liquid was analyzed and prospected.
