Vitrimers are permanently cross-linked polymeric networks comprising dynamic bonds that undergo associative bond exchange. This work describes new strategies to access polyester vitrimers with a wide, tunable range of mechanical properties and relaxation kinetics. Our approach exploits facile synthetic chemistry involving ring-opening polymerization coupled with strategic catalyst design. These advances are anticipated to be of value for a variety of applications including reconfigurable thermosets and composites that leverage vitrimers to promote (re)processibility and recyclability.
