摘　　要：以三亚甲基碳酸酯为单体,通过开环聚合制备聚三亚甲级碳酸酯(PTMC),然后用PTMC改性环氧树脂(E-51)。采用热重分析(TG)、动态热机械分析(DMA)和万能拉力机进行研究。结果表明:改性后环氧树脂固化物比未改性的环氧树脂固化物韧性得到了改善,同时保持了较好的材料使用温度。The trimethylene carbonate was used as monomers to prepare poly trimethylene carbonates （PTMC）. The polymer was used to modifiy epoxy resin to improve the tensile properties. The thermal properties were studied by thermo gravimetric analyzer （TGA） and the mechanical properties were confirmed through universal mechanical machine. The results showed that the modified epoxy resin has higher elongation at break than the pure one.
