Concept of Recycling‐on‐Demand Investigated on Linear Poly(Ester‐Co‐Acetal)s
Macromolecular Materials and Engineering, Volume 311, Issue 1, January 2026.Recycling‐on‐demand (ROD) of polymers into valuable oligomeric building blocks introduces an important step toward a circular economy. Here, poly(ester‐co‐acetal)s (PEAs) serve as a representative model system demonstrating a full proof of concept for the proposed ROD procedure, where the original oligoester is fully retained after degradation and ...
