Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks
Macromolecular Rapid Communications, EarlyView.Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction
Macromolecular Rapid Communications, EarlyView.This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Macromolecular Rapid Communications, EarlyView.Poly(vinylpyrrolidone) creates a quasi‐stable dispersion copolymerization system that enables direct comparison of the dispersed and precipitated polymer fractions. Structural analysis shows that fractionation correlates more strongly with sulfur rank than with molecular weight, revealing how the number of consecutive sulfur atoms in the polysulfide ...

Diverse reactivity of maleimides in polymer science and beyond
Polymer International, Volume 74, Issue 4, Page 296-306, April 2025.This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...
