The Acetone is not essentially “dissolving” the Styrofoam. Right here is what is happing. When styrofoam is positioned in acetone, the extensive polymer strands are dissolved, releasing the trapped air and creating the framework to disintegrate. Nevertheless, the insoluble crosslinked areas of the polymer maintain the polystyrene from dissolving fully, in much the exact way as buoys on nets maintain the total internet from sinking to the bottom of a lake. The moment the acetone evaporates, you are still left with a difficult crosslinked polystyrene residue.
