To determine whether crystallinity impacts the thermomechanical performance of bulk specimens, their storage moduli were determined as a function of temperature in dynamic mechanical analysis (DMA, Figure ). The storage modulus (G') of polymer networks typically decreases with increasing temperatures, signifying a transition from elastic towards more viscous behavior. Thereby, the slope of the curve is a material-specific parameter that varies depending on whether the network undergoes first a glass transition at lower temperatures, where short-range polymer chain motions become accessible, and then a melting transition at higher temperatures, where the crystalline regions lose their long-range order. The change in slopes for the CHTT-containing specimens indicates that the crystallinity of these networks is particularly pronounced.
