The stress-strain plot resulting from averaging all fifteen tests (five systems times three directions) is shown in Figure . The plot suggests that the regime of linear response to deformation ends at 0.02 strain and includes the best-fit line up to that strain value. The restricted time scale accessible by the MD curing procedure and the very short time during which the stress was applied could potentially have resulted in the greater stiffness of our cross-linked sample. Indeed, Figure shows that MD cross-linking completes in a few tens of nanoseconds, which is several orders of magnitude shorter than in a typical experimental curing schedule, usually spanning up to hours. This fact, coupled to the high temperature annealing that was required to obtain a highly cured system in a reasonable computational time, might have introduced some residual strain into the network, which could not be relaxed by post-curing annealing. Nonetheless, the resulting Young's modulus obtained from the slope of the linear response (Figure ) was evaluated as 3.176±0.002
