In the Gordon-Taylor equation, the values of Tg1 and Tg2 correspond to the glass transition temperature of the two components. I have a polymer flavonoid suspension (Soluplus-quercetin). In the DSC soluplus curve, glass transition is observed but no glass transition in quercetin (temperature range 25-350 ° C).
How can I use the Gordon Taylor equation in this case?
To predict the Tg of a polymeric blend, the ratio and the Tg of each component are employed using Fox or Gordon Taylor equations. You may go through the Fox as well; however, the compound's properties need to be identified before using each of which. It is sometimes normal to not detect the Tg of a component using DSC for some reasons. Normally, the Tg derived from DMA and HDT is scientifically much more referable compared to DSC. You can certainly detect the Tg of your component using one of these two analyzing machines. So, you need to give them a try to do so.
