The evolution of the Raman spectrum of 3‐(trimethoxysilyl)propyl methacrylate (TMSPM) during polymerization processes which take place in different chemical reactions is reported. TMSPM is a monomer which has both a methoxide function and a carbon–carbon double bond and is of great interest as precursor to obtain organic–inorganic hybrid glasses hosting chromophores or optically active molecules for a large variety of photonic applications. By changing the reaction conditions, the hydrolysis of TMSPM is achieved by means of polar solvents, or an organic polymerization by using a radical starter: according to the process, the optical, mechanical and chemical properties of the final product show large variations which can be tailored for specific uses. These reactions were monitored through micro‐Raman spectroscopy and a correlation between the vibrational spectra and the degree of organic and inorganic polymerization was obtained.
