Figure 8. DSC heating traces (10°C/min) of i-PS isothermally crystallized at the temperatures listed for 5 hours (except for the 212°C trace where sample was crystallized for 24 hours). Samples were cooled quickly to 80°C after crystallization before being scanned from 80°C to 280°C. All traces same scale, but y-shifted for presentation
