The cover image shows the deformation‐dependent morphology for soft thermoplastic elastomers. It is important to understand their time‐ and temperature‐dependent deformation behavior to enable new applications. Mechanical tests, where molecular weight and composition are systematically varied, give new insights into the molecular dynamics and key parameters that influence the mechanical behavior. A model, presented on page 477 by Michelle Seitz and colleagues, reveals the importance of the physical crosslinks and of the entangled network in ensuring mechanical and temperature resistance.
