Abstract One method to improve the properties of covalent adaptable networks (CANs) is reinforce them with a fraction permanent cross‐links without sacrificing their (re)processability. Here, simple synthesize poly( n ‐hexyl methacrylate) (PHMA) and ‐lauryl (PLMA) containing static dialkyl disulfide (utilizing bis(2‐methacryloyl)oxyethyl disulfide, or DSDMA, as cross‐linker) dynamic dialkylamino sulfur‐sulfur BiTEMPS methacrylate dissociative presented. The robustness (re)processability CANs are demonstrated, including full recovery cross‐link density after recycling. authors also investigate effect content on stress relaxation responses percolated, cross‐links. As PHMA PLMA have very different activation energies respective cooperative segmental mobilities, it shown that dominated by dissociation rather than relaxations backbone segments, i.e., alpha relaxation. In cross‐links, side chains, beta relaxation, critical in allowing for large‐scale governs
