Abstract
Foamed Polystyrene was dissolved in natural organic solvents and was settled by liquid precipitant,the natural organic solvents and precipitant are mutual solvent.A sort of additives was selected to separate solvent and precipitant.Solvent,precipitant,additive are all recycable.The percent recovery of the three solvents can get to above 96%.
