DMF or DMSO are good solvents for dissolving polyamideoxime due to their strong polarity. While completely dissolving polyamideoxime in DMF or DMSO you should initially add small volume of solvent to polyamideoxime, then gradually add more solvent while stirring until the polymer is fully dissolved. Use magnetic stirrer to ensure even distribution and complete dissolution of the polymer. Gentle heating the solvent mixture may be necessary to enhance dissolution.
