Fund Project: This research was financially supported by the National Natural Science Fundation of China (Nos.90606011 and 50472038), Ph.D. Program Foundation of Ministry of Education of China (No.20070255012), Shanghai Leading Academic Discipline Project (No.B603), and the Program of Introducing Talents of Discipline to Universities (No.111-2-04).

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.
