Catalyst and Architecture Effects in Polyester Dynamic Covalent Materials

Polyester networks that include dynamic covalent bonds have attracted significant attention as materials with tunable plasticity. This talk will discuss the role of catalyst strength and building block architecture on dynamic covalent polyester exchange kinetics and mechanical properties. To do so, we introduce a versatile synthetic platform that provides good control over network connectivity through formulation and precursor design. The fundamental insights described herein expand the utility of crosslinked polyesters by broadening the range of accessible material properties.
