Bottlebrush Polyolefin Sulfones as Triggerable and Degradable Pressure‐Sensitive Adhesives

Angewandte Chemie, EarlyView.
A grafting‐through alternating copolymerization strategy yields poly(norbornene sulfone) bottlebrush polymers with high molar mass. These materials function as additive‐free pressure‐sensitive adhesives. The incorporation of cleavable sulfone units enables rapid breakdown under mild alkaline conditions, providing a pathway toward sustainable, high ...
