Catechol-Mediated Glycidylation toward Epoxy Vitrimers/Polymers with Tunable Properties

open access: yes, 2019
This work demonstrates a series of epoxy vitrimers/polymers whose properties can be tuned by incorporating a catechol moiety as a part of the starting bisphenol motif. Glycidylation of the catechol containing bisphenol yielded a single-epoxide derivative
