I have the following queries
1. Which is suitable for determining the polymer blend miscibility-viscometric or solid blended film?
2. which method is superior? Will they provide the same results? Which is the preferred method?
3. Does two method can give contradictory results?
Dear Vipin Cyriac, there are many books on this matter, I don't think there is a precise answer that applies in all situation. May each blend has a specific powerfull characterization technique(s). DSC and TGA are good. The following book gives extended details. My Regards
Characterization of Polymer Blends: Miscibility, Morphology and Interfaces, Sabu Thomas, Yves Grohens, P.
The simplest way to find miscibility of polymer blend is by measuring the glass transition temperature. Therefore, you can use various experimental techniques that are capable of determining Tg.
But sometimes, it becomes difficult to find the miscibility if Tg of the component polymer are very close. Also, if you want to find the miscibility at molecular level you can use positron annihilation lifetime spectroscopy technique.
