聚甲基乙撑碳酸酯（ PPC）是一种新型热塑性脂肪族聚碳酸酯，具有良好的生物降解性、高阻隔性和生物相容性等优点，但其热性能和力学性能较差，通过物理和化学方法改性是提高其性能的重要研究方向之一。本文综述了近年来采用淀粉、纤维素和甲壳素等天然高分子对PPC的改性研究，尤其是天然高分子含量和预处理方法等对复合材料性能的影响，并对PPC/天然高分子复合材料的发展作了总结和展望。

Due to its thermoplastic,superior biodegradable,high barrier property and biocom-patibility properties,Poly(propylene carbonate)(PPC)is widely applied in the fields such as plastic ,medicine and so on.Unfortunately,the thermal and mechanical properties of PPC are poor.To resolve these problems ,a method is blended the PPC with natural polymers such as starch ,cellulose and chitin.The paper reviews the new development of the PPC /natural polymers blend ,and some suggestions are described to pre-pare PPC/natural polymers blend with higher mechanical and thermal properties.
