High Molar Mass Non‐Isocyanate Polyurethanes by Transurethanization of Diols with Isophorone‐Based Bismethylcarbamate

open access: yesMacromolecular Chemistry and Physics, EarlyView.
High molar mass polyurethanes are achieved using potassium carbonate (K2CO3) as a catalyst, confirming that the polytransurethanization route is a good alternative to the isocyanate one. Abstract The synthesis of thermoplastic polyurethanes (TPU) has been associated with sustainability issues, prompting the development of alternative synthesis routes ...

Thiol‐X Chemistry: A Skeleton Key Unlocking Advanced Polymers in Additive Manufacturing

open access: yesMacromolecular Materials and Engineering, EarlyView.
Additive manufacturing and thiol‐X chemistry form a powerful combination for fabricating a diverse array of advanced polymers to address contemporary engineering applications. Thiol‐X reactions offer versatile polymerization mechanisms, “click” reactivity, functional group tolerance, desirable properties, and compatibility over a broad range of 3D ...

Synthesis of Aldehyde Functional Polydimethylsiloxane as a New Precursor for Aliphatic Imine‐Based Self‐Healing PDMS

open access: yesMacromolecular Rapid Communications, EarlyView.
A simple synthetic route to aldehyde functional poly(dimethylsiloxane) (PDMS) through oxidative C─C bond cleavage of terminal epoxide functions by periodic acid is developed. The obtained polymer is introduced as a precursor in the synthesis of aliphatic imine‐based self‐healing PDMS in the form of supramolecular networks or covalent adaptable networks.
