What solvent should be used to precipitate out the copolymer of vinyl pyridine and vinyl carbazole in NMP.I tried deionised water,ethyl acetate everything but unfortunately it doesnt get settle down.
I am getting a milky white but not precipitate,I tried all combinations but still the same.what would be the nature of the precipitate of such copolymer
Can't guarantee success. However, to improve your chances, I would use as low a temperature as you can obtain in your lab (0 degC at most) and add the presumed non-solvent REALLY slowly.
