Outline of Final Research Achievements

We have developed adhesives composed of photolabile crosslinking units and/or side-chains whose polarity can be altered photochemically.
We could not prepare polymers bearing such side-chains due to unstable properties of the monomers that involve polarity-alternable units. However, we succeeded in the preparation of some novel photolabile crosslinkers which could be incorporated in networked polymers. The adhesive force of the polymers reduced on irradiation with UV and visible light. We confirmed the degradation properties by using a photorheometer.
