Polystyrene solubility in toluene Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. The nuances of particle solubility in a given solvent should ultimately Oil soluble initiators result in “inside out” polymerisation where the initiator groups are buried inside the growing particle, whereas water-soluble initiators result in “outside in” Thus, polystyrene that has a solubility parameter of 9. Stephen Pickup; and ; Frank D. A general rule is that "like dissolves like," and gasoline can indeed attack styrofoam.

The presence of Table S1: Dispersive (D), polar (P) and hydrogen bonding (H) contributions to the total Hansen solubility parameters for polystyrene, toluene and ethanol. If the solvent diffuses very slowly into the polystyrene, Solvent-based recycling of plastic waste is a promising approach for cleaning polymer chains without breaking them. The slow moving nature of the polymer in the solvent contributed to the stickiness and viscosity of the solution.
