中文摘要：

聚酯材料是一类具有优良的热力学性能、可以在很宽温度范围内使用的综合性能优异的树脂基体，为进一步提高聚酯材料的高温热氧化稳定性及在不影响热力学性能的基础上赋予材料一些新的特殊功能，硅烷结构引入到聚合物分子链中的杂化聚合物是聚合物合成研究的一个研究热点．我们知道，在航空航天工业中使用的耐高温耐烧蚀材料中重要的一类是有机硅基体树脂．有机硅材料本身的结构特点决定了它除具有良好的阻燃性。外还具有良好的热稳定性、抗氧化性、优良的介电性能等．基于如上所述，本文将有机硅烷结构引入到聚芳酯体系、制备出4种具有良好耐溶剂性并具有优良热稳定性的新型含硅烷结构聚酯聚合物树脂基体，另外还制备出4种具有可溶性、且成膜性良好的聚酯聚合物，对这些含硅烷结构聚酯聚合物进行了初步的热性能表征及溶解性测试．

英文摘要：

Polyesters with silanes in their main chains were synthesized. These polyesters possess interesting properties such as high thermal stability, oxidative stability, low surface energy, water repellency and good dielectric properties. Thermal properties of these silane-containing polyesters were tested by differential scanning calorimetry （DSC） and thermal gravimetric analysis （TGA）. The results show that the polyesters without substitutents have excellent thermal stability and excellent chemical resistance. While polyesters with substituents have good solubility in polar organic solvents such as THF, DMF, DMSO, NMP, DMA and could be made into membrane material easily. These novel silane-containing polyesters could be processed as conveniently as other thermo-plastics and have high application temperature.
