To equilibrate SCPs through "melt" method, the Tg of SCP model is essential for the simulation setting. Estimating Tg through MD simulations strongly depends on the calculation method due to the several factors, e.g., extremely high simulation cooling/heating rates, different fitting procedures, and considerably wide range of transition region. In this work, we used two different methods to estimate the Tg of the SCP models and we observe up to 300 K difference in the calculated values obtained from density-temperature and mean squared displacement (MSD)-temperature graphs, both from the same temperature-sweep simulation trajectories (see SI, section S2.1). For our "melt" simulation settings, we used the values obtained from MSD curves as they give a direct estimation of the temperature at which a clear increase in the dynamics of polymer chains occurs. Thus, 1200 K was chosen to anneal all SCP models above their Tg and a temperature between 700-850 K (depending on the polymer type) for sub-Tg relaxations was used (see SI, Figure ). This emphasises on another advantage of the "soup" method in which a constant high temperature (i.e., 900 K which is well above the melting points of all repeat units) can be used for any SCP and the Tg estimation step (which is a prerequisite to the conventional "melt" equilibration) can be avoided.
