Question: Polymer D and Polymer E can be combined to create a blend that is both stable and totally compatible. Polymer D has a Tg of

Polymer D and Polymer E can be combined to create a blend that is both stable and totally compatible. Polymer D has a Tg of 110 oC, whereas Polymer E's DSC curve indicates a rather moderate glass transition at temperatures lower than 110 oC. It's difficult to get an accurate Tg value for Polymer E because of the weak transition. Despite multiple attempts utilising various heating rates, heat treatments, and sample sizes, a strong glass transition of the Polymer E for accurate Tg value calculation has yet to be achieved. Suggest a solution to the problem above. Your suggestion must include the use of DSC only. Explain and clearly show one set of example calculations involved.
