Notes:
The mechanism by which TiO2 exerts a phototendering effect on nylon 66 photodegradation has not been previously explained. To aid in the elucidation of this mechanism, the wavelength dependence curves of photodegradation of nylon 66 both with and without TiO2 have been accurately determined. These data, in conjunction with reflectance and phosphorescence measurements, indicate that the phototendering effect of TiO2 proceeds by a chemical rather than an energy transfer mechanism.
