Enhancement of the rates of cationic polymerizations initiated by onium salts has been achieved through the use of oligomeric and polymeric electron-transfer photosensitizers derived from a polymerizable compound substituted with a polynuclear aromatic group, including epoxides, oxetanes, and ethylenically unsaturated compounds. The polymerizable compound is substituted with residues derived from anthracene, naphthalene, perylene, pyrene, fluorene, carbazole, indole, benzocarbazole, acridone, phenothiazine, and thianthrene, particularly carbazole.
通过使用由可聚合化合物取代的多核芳香基团衍生的寡聚物和聚合物电子转移光敏剂,包括环氧化物、氧杂环丙烷和乙烯基不饱和化合物,已经实现了由离子型盐引发的阳离子聚合速率的提高。可聚合化合物被取代为来自蒽、萘、苝、芘、芴、咔唑、吲哚、苯并咔唑、芴酮、苯并噻吩的残基,特别是咔唑。
