摘　　要：A novel POSS-containing organic-inorganic hybrid crosslinked polymer was prepared by hydrosilylation reaction of octahydridosilsesquioxane （TsHs） with 4,4＇-bis（4-altyloxybenzoyloxy）phenyl （diene A）. Its structure and property was characterized by FFIR, 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.A novel POSS-containing organic-inorganic hybrid crosslinked polymer was prepared by hydrosilylation reaction of octahydridosilsesquioxane （TsHs） with 4,4＇-bis（4-altyloxybenzoyloxy）phenyl （diene A）.
