以4，4 ′-二（4-烯丙氧基苯甲酰氧基）苯基（二烯A）和八氢倍半硅氧烷（T8 H8）为原料，通过硅氢加成反应合成了一种新型的含POSS的有机-无机杂化交联聚合物。采用FTIR、29 Si NMR、TGA和椭偏仪等手段对其结构和性能进行了表征。结果表明，该杂化聚合物具有较高的热稳定性和较低的光频介电常数（1.97）。
A novel POSS-containing organic–inorganic hybrid crosslinked polymer was prepared by hydrosilylation reaction of octahydridosilsesquioxane (T8H8) with 4,4′-bis(4-allyloxybenzoyloxy)phenyl (diene A). Its structure and property was characterized by FTIR,29Si NMR, TGA and ellipsometer, respectively. The results show that the hybrid polymer possesses high thermal stability and low dielectric constant of 1.97 at optical frequencies.
