Aromatic disulfide metathesis has been reported as one of the very few dynamic covalent chemistries undergone at room-temperature. Here, bis(4-aminophenyl) disulfide is effectively used as a dynamic crosslinker for the design of self-healing poly(urea-urethane) elastomers, which show quantitative healing efficiency at room-temperature, without the need for any catalyst or external intervention.
