摘　　要：采用含八乙烯基的POSS为原料,与不同的聚氨酯预聚体进行共聚,合成了一系列POSS基高分子胶粘剂材料。通过表面红外(ATR)、广角X射线衍射(WAXD)和动态力学分析(DMTA)等方法表征了杂化胶粘剂的热性能。A series of POSS based hybrid polymer adhesive materials were synthesized by copolymerization of POSS containing eight vinyl groups as the raw material and different polyurethane prepolymers. The thermal properties of the hybrid polymer adhesives were characterized by attenuated total reflection （ATR）, wide-angle X-ray diffraction （WAXD） and dynamic mechanical thermal analysis （DMTA）.
