Dynamic bond elastomers are attracting attention because of their self-healing properties and toughness. Using coarse-grained molecular dynamics simulations, we studied how the sequence of binding sites and reaction time before elongation affect their mechanical properties. Our simulations with random, regular, and semiregular sequences indicated that reaction time influences the formation of crosslinking structures. Elastomers with a regular sequence and shorter reaction time had a higher modulus due to more interchain crosslinks. These findings provide new insights into the mechanical behavior of dynamic bond elastomers.
