Outline of Final Research Achievements

A new divinyl monomer bearing rigid bisorthoester moiety was synthesized from rice bran-derived myo-inositol via a synthetic route including stereochemical conversion of hydroxyl group of myo-inositol. The vinyl groups of the monomer underwent radical addition with thiols efficiently to give the corresponding adducts quantitatively. In addition, an analogous bisorthoester prepared as a model of target polymers was efficiently hydrolyzed under acidic conditions. These results demonstrated the feasibility of synthesis of rigid rod-like and acid-labile polymers and their application to photoresist materials.
