Fluorescence Studies of Photolytic Products of Benzophenone During the Photoinitiated Crosslinking of Polyethylene and its Model Compounds

Photolytic product of benzophenone （BP） during the photoinitiated crosslinking of polyethylene and its model compounds has been detected and identified for the first time by the fluorescence spec-troscopy. The results showed that main product of BP photoreduction is benzopinacol, which provides new experimental evidence for elucidating the mechanism of the photoinitiated crosslinking of polyethylene.
