Hi, I am using the following experimental route to synthesize a polymer, but when the experimental section is wholly done, I cannot find any polymers in the solution. What should I do to extract the polymers from the DMSO solution?
Experimental Route: :
3.5 g of 1,4-butanediol diacrylate (17.7 mmol) and 1.5 g of 6-amino caproic acid (11.4 mmol) were firstly mixed in 10 mL of 50% (v/v) DMSO aqueous solution, followed by vigorously stirring for 12 h at 90 °C in a safe dark place. Subsequently, end-capping reaction was performed by the addition of 10% (v/v) amino solution, ethylenediamine, into the polymer/DMSO solution."
Dear Hamidreza Moazzeni ,
You should find a non-solvent for your polymer that dissolve both the reagents and DMSO and precipitate the resulted polymer,
try with cold Methanol as a non-solvent....
Dear all, please check this similar RG thread. My Regards

Dear Abdelkader BOUAZIZ , I, ve read the articles you have mentioned before, but still, I have the same problem. Could you please tell me how I should know if the monomers have been polymerized?
Dear Hodhaifa Derdar, Thank you for your advice. is it helpful to centrifuge the solution?
