Development of High Performance Photo-Curable Polymers and Oligomers Using Novel Reaction of Ocetane Compounds

The authors recently found many new addition reactions of oxetanes with certain reagents such as phenols and carboxylic acids using certain quaternary onium salts or crown ether complexes as catalysts. More recently, we also found new anionic ring-opening polymerization of oxetaries containing pendant hydroxyl groups and alternating anionic ring-opening copolymerization of oxetanes with cyclic carboxylic anhydrides using appropriate catalyst system. These reactions have been widely applied to the synthesis of polymers and thermo-setting reactions of oxetane resins. In this paper, we would like to introduce the application of these new reactions for the synthesis of high performance photo-curable polymers and oligomers containing pendant or terminal (meth)acryloyl groups. The authors also report the photochemical property of the resulting polymers and oligomers. Furthermore, the authors would like to talk about the synthesis of certain calixarenes and poly(imide)s containing oxetane groups as high performance materials and their photochemical reaction.
