Abstract As a terpene‐based conjugated diene, β ‐myrcene (Myr) is promising renewable building block for synthetic rubbers. However, the high entanglement molecular weight of poly(Myr) limits its mechanical properties and applications. This work aims to improve dimensional stability recyclable bio‐based Myr elastomers by incorporating vitrimer chemistry copolymer self‐assembly. Linear prepolymers statistical diblock terpolymers Myr, styrene (S) ‐ketoester functional (acetoacetoxy)ethyl methacrylate (AAEMA) were synthesized using nitroxide‐mediated polymerization. The resulting (P(S‐ co ‐Myr‐ ‐AAEMA)) (PS‐ b ‐P(Myr‐ had comparable number‐average weights ( M n ~ 20–27 kg mol −1 ) similar overall compositions. PS‐ ‐AAEMA) underwent microphase separation into lamellae, as confirmed small‐angle X‐ray scattering atomic force microscopy. Vinylogous urethane vitrimers formed crosslinking AAEMA units in with vegetable oil‐derived difunctional amines (Priamine 1075). networks could be remolded hot pressing at 125 °C least 4 cycles while retaining thermomechanical properties. exhibited tensile stress 3.1 ± 0.6 MPa, which was four times higher than that P(S‐ ‐AAEMA). also nearly ten hardness, strain break 90%), compared terpolymer‐based vitrimer. addition glassy PS domains effectively anchored network, 18–35% lower creep highlights potential Myr‐based creating robust, elastomers. © 2025 Author(s).
