Materials and methods
Test guideline

- Principles of method if other than guideline:
- Modulated DSC was used for glass transition analysis during this study and is a technique in which a sinusoidal temperature oscillation is overlaid with the standard linear DSC experiment. This increases resolution and allows for thermal events due to changes in heat capacity to be separated from thermal events due to kinetics. A glass transition (Tg) is a thermal event due to changes in heat capacity and therefore if a given specimen has a Tg it will occur in the reversing heat flow. This technique also removes any thermal history from the thermal event therefore a second heat cycle is not needed. The midpoint is used to represent the glass transition, although the glass transition occurs over a temperature range.
