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.

分别采用FTIR、~1H-NMR、~(29)Si-NMR和UV等方法对五个系列POSS基高分子材料进行了表征，证实POSS已与共聚单体发生了聚合反应；并通过红外标准曲线和紫外标准曲线以及核磁积分面积对共聚物中POSS的含量进行了计算，发现可以通过投料比来控制共聚物的组成。
