Curing and viscoelasticity of vitrimers

, 2017
We present an experimental investigation of the curing kinetics and viscoelasticity for a number of “vitrimers” recently developed by Leibler and coworkers.1-3 Vitrimers are covalently crosslinked networks that can relax stress at elevated temperatures ...

Exploring Self‐Repair Capabilities of ATSP Vitrimers for Crack Mitigation in Aerospace Applications

Macromolecular Materials and Engineering
Vitrimers, although categorized as thermosetting polymers, differ from traditional ones in that their thermally induced crosslinks undergo reconfiguration through covalent bond exchanges in response to thermal stimuli.
