| Outline of Final Research Achievements |
In this study, we developed an easy-peelable pressure-sensitive adhesive (PSA) technology with high heat resistant that can be used for recycling. We synthesized photolabile crosslinkers that have both polymerizable and photodegradable moieties in a single molecule. Using these crosslinkers, we were able to prepare PSAs with dismantleability. We found that the PSAs were stable up to 200°C, and that the peel strength decreased with photo-irradiation and heating above 250°C. It was found that these PSAs can be used as an easy-peelable PSAs adhesive with heat resistance.
