How to remove DMF (dimethylformamide) from the structure of a polymer compound without using a vacuum oven?
In some cases just drying in ventilation laboratory hood with small heating can be work out. But be carreful becasue DMF is highly inflammable liquid and ventilation should be ON during heating even at small temperatures.
