Figure 3: Vinylogous urethane vitrimer elastomers.
From: Chemical control of the viscoelastic properties of vinylogous urethane vitrimers

The monomers (priamine 1, tris(2-aminoethyl)amine 2 and acetoacetylated pripol 3) were used for the synthesis of elastomeric vitrimers together with an additive (Table 3).
