We have prepared N, N-dimethylacrylamide oligomer possessing end-capped nitrile units/silica nanocomposites by the sol-gel reactions of tetraethoxysilane with silica nanoparticles in the presence of the corresponding oligomer, which was synthesized by using an azo-initiator having nitrile groups, under alkaline conditions.  These obtained nanocomposites were found to exhibit no weight loss corresponding to the content of oligomer even after calcination at 800 oC.   Furthermore, we have succeeded in preparing N, N-dimethylacrylamide oligomer possessing end-capped nitrile units/silica nancomposites-encapsulated a variety of low molecular weight aromatic compounds (Ar-H ) such as bisphenol-A, bisphenol-F and 1,1'-bi-2-naphthol by the sol-gel reactions of tetraethoxysilane with silica nanoparticles in the presence of Ar-H  and the corresponding oligomer. It was demonstrated that these end-capped nitrile units-containing oligomer/silica nanocomposites-encapsulated Ar-H  can exhibit no weight loss behavior corresponding to the contents of Ar-H  even after calcination at 800 oC.
