The mechanisms of hydrolysis and condensation of a silane coupling agent, γ‐methacrylo‐xypropyltrimetoxysilane (γ‐MPTS) were investigated by the use of both 13 C and 29 Si nuclear magnetic resonance (NMR) spectroscopies. The NMR peaks of the hydrolyzed monomer and condensed polymer were assigned readily. The rate of hydrolysis and condensation of γ‐MPTS was dependent on water content. On the basis of the time‐dependent behavior of these peaks, the mechanisms of hydrolysis and condensation were clear.
