The observed collapse of the density curves 𝜌(𝑇) calculated from the simulations onto one master curve can be related to the universality of glass transition, as expected. As shown in the middle panel in Figure , the transformation depends on three fitted parameters 𝑎, 𝑏, and 𝑐. While 𝑏 and 𝑐 are used to move the center of each hyperbolic-like curve to the same point, the rescaling of the temperature axis by a factor 𝑎 maps the parts for 𝑇 < 𝑇 , and for 𝑇 > 𝑇 , onto a single master curve at the same time. Closer analysis shows that this is only possible when the ratio of the derivatives of 𝜌(𝑇), calculated for the linear part of the curve below and above the glass transition, does not depend (up to numerical errors) on the curing percentage.
