Epoxy-Anhydride Vitrimers from Aminoglycidyl Resins with High Glass Transition Temperature and Efficient Stress Relaxation.

Epoxy-anhydride vitrimers are covalent adaptable networks, which undergo associative bond exchange reactions at elevated temperature. Their service temperature is influenced by the glass transition temperature () as well as the topology freezing transition temperature (), at which the covalent bond exchange reactions become significantly fast. The present work highlights the design of high- epoxy-anhydride vitrimers that comprise an efficient stress relaxation at elevated temperature.
