Raman spectroscopy was applied to study the reactions between amine and epoxy groups, which had been expected to proceed during synthesis of hybrid polymer based on three monomers: 3-aminopropyltrimethoxysilane (APTES), 3-glycidyloxypropyl-trimethoxysilane (GPTS) and methacryloxy-propyltrimethoxysilane (MPTS). Efficiency of the investigated reaction determines the molecular structure of the organic network and consequently - mechanical and optical properties of manufactured material. An optical system developed for the real-time Raman monitoring was connected with typical glass reaction vessel and non-invasive measurements were made. Additional FT-Raman investigation was carried out to confirm obtained results. Transformation of primary amine as well as epoxy ring opening was confirmed and role of catalyzers was discussed.
