Abstract: In this paper, the PMMA/TiO2 hybrid polymeric materials were prepared by the sol-gel process.In order to introduce the chemical bond between the organic polymer chain and inorganic network in the hybrid, the trimethoxysilyl functional group was introduced on the polymer side chain by copolymerization with 3-(trimethoxysilyl) propyl methacrylate (MSMA).The result of solvent extraction shows that the gel content in the hybrids with the presence of chemical bond through the reaction of MSMAwith titanium(IV) butoxide is much higher.The chemical structure of the hybrid was analyzed by the FTIR, and the effect of inorganic content on the properties of materials were investigated by TGAand DSC.
