Figure 1.

The three-dimensional molecular configuration of the crosslinked polymers consisting of 180,000 beads under uniaxial tension at T = 0.1 when the strain is equal to 0.8 (the three atom types of the inset represents middle bead (red), end bead (blue), and the crosslinked bead of the middle bead (yellow), respectively). (a) Configuration of linear polymers (two type beads (middle beads and end beads) can be found in the configuration); (b) configuration of crosslink density of 1.1%; (c) configuration of crosslink density of 4.4%; (d) configuration of crosslink density of 17.3%; (e) configuration of crosslink density of 37%; and (f) configuration of crosslink density of 58.7%.
