Materials with tunable modulus, viscosity, and complex viscoelastic spectra are crucial in various applications but it remains challenging to design polymer networks with predicted hierarchical relaxation processes. Here, the authors synthesize networks with both pendant and telechelic architectures using mixed orthogonal dynamic bonds to understand how the network connectivity and bond exchange mechanisms govern the overall relaxation spectrum.
