i disolved my polymer (my polymer is sold)in DMSO solvent i remove this solvent from my polymer but i stell have some traces from the solvent in my polymer make my polymer as a lotion but i need my polymer in a sold state,pls any ideia
DMSO is very tenacious! Since NO OTHER solvent dissolves the polymer, I would add an alcohol (methanol or ethanol) and precipitate the polymer,]; then wash the polymer with more alcohol. Water will work, but is more difficult to remove from the polymer in the drying step.
