摘要：

We developed novel photobase generators (PBGs) that generate radicals and aliphatic amines simultaneously. We demonstrated that the PBGs induced radical polymerization and hydrolytic polycondensation. A film of poly[(methacryloxypropyl)silsesquioxane] (MA-PS) was cured in the presence of a PBG upon UV-light irradiation at 254 mu. This result showed that radical polymerization of methacryloyl groups of MA-PS with the photogenerated radicals and the crosslinking reactions based on the base-catalyzed condensation reactions of alkoxy-silyl units of MA-PS proceeded. Furthermore, pencil hardness showed HB at 1.0 J cm(-2) and 4H at 21.6 J cm(-2) without heat treatment.
