Precipitating a polymer solution into methanol
This is the basic technique for precipitating a polymer solution. This is done to purify the polymer by removing unreacted monomers, solvents, catalyst, and other low molecular weight materials. Methanol is widely used, but other solvents such as hexane may useful for certain systems. The objective is to add the polymer slowly, to a much larger ...
