    • As seen in the experimental section also pure PS samples are cooled down at 20 K min1 before aging. However, the recovered enthalpy in pure PS is marginally sensitive to the cooling rate. Thus, the recovered enthalpy for pure PS is the one that mostly resembles the recoverable enthalpy after a perfect quench from 375 K. Pure PS recovered enthalpy at 363 and 366 K is slightly lower than the recoverable one after a perfect quench. This implies a slight underestimation of the diffusion coefficient at these temperatures resulting from the application of the model
