Caption : (a) specific volume ν and (b) thermal expansivity α as a function of temperature of different systems. black squares represent asso-cans of telechelic short chains with 5-mer and crosslinkers, red dots represent diss-cans of 5-mer and crosslinkers, green triangles represent pendant crosslinked asso-cans of 50-mer, and blue triangles represent pendant crosslinked asso-cans of 50-mer and crosslinkers. the activation energies in all systems are <i>e</i><sub>a</sub><sup>kin</sup>=10 <i>ε</i><sub>lj</sub>. <i>t</i><sub>g</sub> is inferred by the extrapolated crossover of two fitted lines. <i>t</i><sub>v</sub> is inferred by the local minimum of thermal expansivity.

Caption : the number of formed bonds and broken bonds as a function of time. the red solid dots represent the number of formed bonds at the interface, the red hollow dots represent the number of broken bonds at the interface, the black solid and hollow squares represent the number of formed bonds and broken bonds in bulk, respectively.
