The fabrication of polyolefin thermoplastic elastomers (P-TPEs) with superior robustness (high strength and high toughness) is challenging. Integrating dynamic (reversible) noncovalent cross-links into P-TPEs may solve the trade-off between toughness permanent (irreversible) cross-linking elasticity. Here, we report a two-step synthesis that contain flexible polymer chains different thiol branches (less than 2.0 mol %) cross-link through hydrogen bonding. cross-linked polymers exhibit negligible hysteresis after being circularly stretched 10 times at low strain, is, few H-bonds break per cycle delocalize stress concentration to withstand load delay premature fracture. At large deformation, dissipate vast energy by sacrificial H-bond scission: reform prevent failure dictate simultaneously fracture (σ up 10.2 MPa) (UT 22.6 MJ/m3). Meanwhile, resultant materials present stiffness (E ≈ 2.5 MPa), good extensibility (ε > 600%), elastic recovery 90% even 680% strain. polyolefins are readily (re)processable, tensile properties largely recovered remolded least twice.
