Abstract
Much attention has been paid to new development of photo-functional network polymers. This review article introduces synthesis and some properties of new photo-curable polymers, oligomers, and monomers. Thermally stable new polyimides with pendant epoxide or vinyl ether moieties have been synthesized. Photo-curable calixarenes containing (meth) acrylate groups, which are new (meth) acrylate monomer having excellent thermal stability similar to polyimides, have been synthesized by the reaction of p-methyl calix [4] arene with certain (meth) acrylate derivatives. Some poly-functional vinyl ether monomers and polymers have also been prepared by the addition reaction of glycidyl vinyl ether with poly-functional acyl chlorides, by the isomerization of the corresponding allyl ethers and so on. Furthermore, it was reported that certain photo-crosslinked functional polymers such as liquid crystalline polymers and NLO polymers containing cinnamoyl groups have ordinarily better functionality than the corresponding linear polymers. Soluble or insoluble polymers containing norbornadiene moieties in the main chain or the side chain, which were used for photo-energy exchange polymers, have been synthesized and studied their photochemical property and storage property of the thermal energy.
