I'm wondering what is going to happen in the following scenario:

If I have a component, say a polymer, which I dissolve in a solvent like THF. This solvent is perfectly miscible with water, but the polymer does not dissolve in water.

So what is gonna happen if I pour the polymer/THF solution in a large amount of water?

I think that the THF won't be able to surround the polymer molecules anymore, so there is no THF matrix anymore and polymer precipitates. But is this true ?

Depending on the concentration of the substance in THF you may get two layers forming, An aqueous layer and a THF/polymer layer.
