In this research, hybrid materials based on poly{(butyl methacrylate)‐ co ‐[(3‐methacryloxypropyl)trimethoxysilane]} were synthesized via a sol‐gel process. The physical properties of the materials with various silica contents were investigated. It was found from infrared spectra data that the organic‐inorganic interface was bonded not only by covalent bonds but also by a portion of hydrogen bonds. A second glass transition temperature appeared when there was more than 60 mol‐% silane in this hybrid system. The thermogravimetric data illustrated that all the hybrid materials decomposed in three stages, whereas the homopolymer of butyl methacrylate decomposed in only one stage. It is deduced that when the silane content is 60 mol‐% or more, part of organic chain segments was found restricted by the inorganic phase.
