fourier-transform (ft) infrared spectroscopy has been applied to study the hydrothermal degradation of various coupling agents on e-glass fibers. the coupling agents studied include gamma-methacryloxypropyltrimethoxysilane, vinyltrimethoxysilane, and cyclohexyltrimethoxysilane. the amount of coupling agent on e-fibers was measured as a function of immersion time in water at 80 degrees c. structural changes were also followed by obtaining ft-ir difference spectra of the coupling agent on the glass fiber surface silanes desorb quite differently depending on the organofunctional groups. the resistance to desorption is strongly influenced by the organization of the silane interphase as well as the solubility of the silane in water
