聚甲基乙撑碳酸酯的改性研究现状与进展

Research status and progress of modifi-cation of poly(propylene carbonate)

二氧化碳(CO2)和环氧丙烷(PO)合成的脂肪族聚甲基乙撑碳酸酯由于具有良好的生物降解性,生物相容性和气体阻隔性等优点引起了广泛的关注。但由于热性能、力学性能较差限制了其应用,为了扩大聚甲基乙撑碳酸酯(PPC)的实际应用,必须对其进行改性。从物理改性和化学改性两方面综述了近年来PPC改性方面的研究现状,并对其未来发展作了展望。

Aliphatic poly（propylene carbonate） （PPC）, synthesized from propylene oxide （PO） and carbon dioxide （CO2） ,has been paid much attention due to good biodegradability, bioeompatibility and gas barrier properties. The drawbacks of poor mechanical properties and thermal stability limited its practical applications. It was necessary to carry out modification in order to expand the practical application. Research progress in modification of poly（propylene carbonate） were reviewed from aspects of physical and chemical, and the developing tendency was prospected.
