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.
