| Outline of Final Research Achievements |
We proposed dismantlable adhesive systems that required both strong bonding without deterioration during use and quick and easy debonding responding to dual stimuli, such as UV irradiation and subsequent heating. High-molecular-weight acrylic ester polymers with well-defined sequence structures were synthesized using living radical polymerization and their adhesive properties were controlled by the side-chain transformation and subsequent polymer reactions in the response to the dual external stimuli in the presence of a photoacid generator. The enhanced cohesive force of adhesives, quick response during debonding process, and control of failure modes were achieved by the precise control of adhesive polymer materials.
