The POSS-based hybrids were characterized by FTIR,~1H-NMR,~(29)Si-NMR and UV. The POSS content in the hybrids were determined using three kinds of different methods and could be effectively controlled by varying the POSS feed ratio.4. It was estimated that about 5~8 vinyl groups in POSS participated in the copolymerization reactions by the ~1H-NMR spectra.
