摘要：
Strips of polystyrene held under ultra high vacuum have been exposed to 240-600-nm ultraviolet radiation, and the resultant photodegradation products were identified by mass spectrometry. These in situ experiments provide the first ever conclusive evidence for phenyl radical formation during the photolysis of polystyrene film.
