Imagine I mix those two polymers together and want to dissolve only one of the mentioned polymers. What are the best options I have for a solvent? This is not my field of expertise, so any tips are very much appreciated.
Dear Robbin Meester, first you have to find an issue to the incompatibity of these two polymers. They phase separate while cooling down. How are you going to maintain them ? Are you using a third component to insure compatibility ? My Regards
EVA is difficult to dissolve and maintain as a solute at room temperature. It will dissolve in toluene at higher temperatures but will precipitate on cooling. Polypropylene is much easier to dissolve and maintain as a solute. Try an non polar solvent such as hexane. A hexane toluene mix should dissolve the blend at elevated temperature and allow the EVA to precipitate on cooling.
Thanks for the tip! I want to dissolve one of the polymers to see what the morphology is of this blend. This is of interest because of the incompatibility of these polymers. Therefore if I dissolve one of the polymers, the remaining polymer would give a clear picture of the morphology.
