Abstract (en)
[origin: FR2864544A1] A method for dissolving expanded polystyrene (I) involves (a) contacting (I) with first, initial solvent(s) (S1) for converting (I) from an expanded solid into a gel; and (b) contacting the gel with second, complementary solvent(s) (S2) for dissolving the gel to form a true solution (A). Independent claims are included for: (1) a composition for the dissolution of (I), comprising the solvents (S1) and (S2); and (2) the true solutions (A) obtained by the process.
