Recyclable ethylene-vinyl acetate copolymer vitrimer foams

Current practices in the production and disposal of polymers follow an unsustainable trend. Foamed ethylene-vinyl acetate copolymer (EVA) is no exception as chemical cross-linking limits recyclability. Here, we demonstrate that we can readily control the kinetics of the cross-linking networks by changing the usage and variety of linkages with the introduction of reversible transesterification to construct EVA vitrimer. EVA vitrimer foams are...
