摘要：
The influence of FeCl3 on photochemical and thermal degradation of PMMA and PS has been investigated using viscosimetry, IR and UV-Vis spectroscopy as well as derivatographic analysis. Acceleration effect of FeCl3 on photooxidative degradation PMMA and on the chromophores formation in PS was found. A significant decrease of the thermal stability in UV-preoxidized PMMA, but only a small one in irradiated PS, was observed.
