A novel POSS-containing organic-inorganic hybrid crosslinked polymer was prepared by hydrosilylation reaction of octahydridosilsesquioxane(T_8H_8) with 4,4’-bis(4-allyloxybenzoyloxy)phenyl(diene A).Its structure and property was characterized by FTIR,~(29)Si 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.
