Degradable Adhesives as Sustainable Alternatives to Acrylics via Ring-Opening Radical Polymerization of Vinylcyclopropanes Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2025-02-10 Daewhan Kim, Changhoon Yu, Min Sang Kwon
Acrylic pressure-sensitive adhesives (PSAs) are loosely crosslinked polymer networks widely used across various industries. However, the network structure and inert nature of the acrylic polymer backbone present sustainability challenges. To address these issues, efforts are being made to incorporate degradable units into the polymer backbone. Yet, two key obstacles remain: i) the polymer does not
