Abstract: Poly（propylene carbonate）（PPC）is a new completely biodegradable thermoplastic aliphatic polycarbonate. Blending with other polymers is an effective way to improve the overall properties of PPC based materials. From the viewpoints of synthesis，performance characteristics and applications of PPC， advances in solvent blending and melt blending modification of PPC with degradable polymers，non-degradable polymers and inorganic particles for nearly a decade are reviewed and the developing tendency of PPC is discussed.

摘要： 聚碳酸亚丙酯（poly propylene carbonate，PPC）是一种新型可完全生物降解的热塑性脂肪族聚碳酸酯。与其它聚合物进行共混改性是改善PPC基材综合性能的有效手段。本文从PPC的合成工艺、性能特点和应用出发，综述了近十年来PPC与可降解聚合物、非降解聚合物、无机粒子等进行溶剂共混和熔融共混改性的研究进展；并对PPC将来的发展作了展望。
