A vitrimer-like polyurethane is investigated for its Tan-delta plateau phenomenon (i.e., a quasi-steady high Tan-delta value over a long temperature range). It is concluded that this plateau is associated with cross-linking dissociation, but on the condition that this dissociation process should be...
