Abstract

L'invention porte sur un système de solvant amélioré utile pour affaisser un polystyrène alvéolaire et comprenant pour 100 parties en poids d'un ester d'acide organique dibasique sélectionné dans le groupe comprenant un adipate de dialkyle, un glutarate de dialkyle, un succinate de dialkyle et des mélanges de ceux-ci. Ces groupes alkyle sont identiques ou différents et possèdent de 1 à 12 atomes de carbone, au moins un cosolvant sélectionné dans le groupe comprenant (i) de 10 à 66,7 parties en poids d'éthylène glycol, (ii) de 10 à 66,7 parties en poids de propylène glycol, (iii) de 17,6 à 42,8 parties en poids de carbonate de propylène, (iv) de 53,8 à 66,7 parties en poids de diméthylsulfoxyde, (v) de 53,8 à 66,7 parties en poids de diacétone-alcool, et (vi) de 42,8 à 66,7 parties en poids d'isopropanol. Ce système de solvant est notamment utile pour le recyclage et la récupération du polystyrène.
