Coarse‐Grained Simulations Rationalize Thermosensitivity and Hydrolytic Degradation of Vinyl Copolymers Obtained by Radical Ring‐Opening Polymerization

open access: yesAngewandte Chemie, EarlyView.
Coarse‐grained (CG) molecular dynamics simulations were used to predict the upper critical solution temperature of copolymers obtained by radical ring‐opening copolymerization of cyclic ketene acetals and vinyl monomers, and to account for their unique degradation kinetics under physiological conditions by evaluating the solvation of their ester groups.

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

open access: yesAngewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Bottlebrush Polyolefin Sulfones as Triggerable and Degradable Pressure‐Sensitive Adhesives

open access: yesAngewandte 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 ...

Supramolecular Mechanophore Additives Enable Mechanochromic Hydrogels

open access: yesAngewandte Chemie, EarlyView.
A supramolecular loop‐forming mechanophore featuring a quencher and an emitter is incorporated as a water‐soluble macromolecular additive into hydrogels. In the stress‐free state, intramolecular charge‐transfer interactions fold the loop and quench fluorescence.
