I have done some tests of polysulfone synthesise using the nucleophilic substitution route. in a some of the tests, DMSO was the only solvent that was used in the synthesise process. However I am wondering how the final synthesised polysulfone can be coagulated from the final reaction mixture?
I am wondering if drying the final product is a good way to get rid of the other components and collect the polysulfone?
Or
If I can use any reagent as the coagulant of polysulfone to coagulate this polymer from the solvent (reaction mixture)?
Thanks for your attentions.
Just precipitate the polymer in a DMSO miscible hydrocarbon solvent
Hi, I understand with you, follow the instruction of Nodirali by precipitating the polymer in a DMSO miscible hydrocarbon solvent, Goodluck.
Thanks @ Nodirali S. Normakhamatov and @ Emmanuel Ifeanyi Obeagu for your attention and suggestions.
Would you mind nominate a DMSO miscible hydrocarbon solvent as you mentioned?!
I also would like to say that I used ethanol to coagulate the polymer however no coagulation was seen. I am not sure why nothing happened, whereas in the literature ethanol was nominated as a coagulant reagent. I have done all these reactions n high shear rate, I am wondering if this high shear rate is affecting the coagulations behaviour.
Thanks for your attention.
Dear Aghil Igder,
At the first, are you sure that the polymerization has occurred? If so, what about its molecular weight? Are they not oligomers? You should choose an organic solvent as a coagulant among non-polar ones, which miscible with DMSO.
