【Abstract】 Transparent organic-inorganic hybrids of PMMA and SiO 2 were prepared through BPO initiating polyaddition and acid catalyzing sol-gel process using MMA, TEOS and silane coupling agent KH-570. The preparation conditions were discussed and the nanocomposites were characterized by IR,SEM and TG. In addition, the transparence, hardness and heat-resistant propreties of the composites were also investigated.更多还原
