How polystyrene can dissolve in toluene according to solubility parameter |
|
Answer» When you DISSOLVE polystyrene in TOLUENE and PRECIPITATE the polymer solution into METHANOL, you get a polymer that is stuck together. However, when polystyrene is dissolved in THF and PRECIPITATED in methanol, the polymer precipitates out in strands. |
