Poly(methyl methacrylate)/POSS organic/inorganic hybrid materials are synthesized using atom transfer radical polymerization(ATRP),in which octa(γ-chloropropyl)silsesquioxane(OCP-POSS) is used as ATRP initiator.GPC,DSC and TGA are employed to characterize the structure and properties of the obtained composites.The results display that the hybrid composite with narrow molecular weight distribution is prepared respectively in three different solvent including toluene,isopropyl alcohol and N,N-dimethyl formami...
