Ki. Ito et al., NOVEL PHOTO-CROSS-LINKING OF POLYMERS BEARING PENDANT ACYLOXYIMINO GROUPS IN THE PRESENCE OF P-BENZOQUINONE, Macromolecular rapid communications, 17(4), 1996, pp. 203-207
Films of polymers bearing pendant acyloxyimino (AOI) groups become ins
oluble when irradiated by ultraviolet light in the presence of p-benzo
quinone. Post-heating of these films after irradiation also induces fu
rther the insolubilization. In the photocrosslinking, it is deduced th
at p-benzoquinone serves not only as sensitizer for the decomposition
of AOI groups but also as crosslinker during the photo-irradiation and
heating after irradiation.
