Dynamic covalent chemistries are an exciting class of reactions that have gained attention on account of their ability to access reprocessable and healable polymer networks. We have developed a series of dynamic covalent networks based on reversible thia-Michael reactions (Fig A) and disulfide exchange reactions (Fig D).. Yana . Zabrodskaya. , Alexey .
