Patent

CA 2297807

The invention concerns the transformation of expanded polymers, in particular styrene polymers of the polystyrene type and styrene copolymers. More particularly it concerns a method for transforming polymers in an expanded solid state into a non-expanded amorphous state in the form of a re-usable malleable pasty magma. The method comprises a step for treating the polymer with a transforming solution containing a solvent, a non-fatty lubricant and optionally an alcohol. The invention concerns the transformation method proper, the transforming solution used in said method, the device for implementing said method and the magma resulting from implementing the method.

L'invention concerne la transformation de polymères expansés, notamment de polymères styréniques de type polystyrène et de copolymères styréniques. Plus particulièrement, la présente invention concerne un procédé de transformation de polymères d'un état solide expansé à un état amorphe non expansé sous forme d'un magma pâteux et flexible réutilisable. Le procédé comprend l'étape de traitement du polymère avec une solution de transformation comprenant un solvant, un lubrifiant non gras et éventuellement un alcool. L'invention concerne le procédé de transformation proprement dit, la solution de transformation utilisée dans ce procédé, le dispositif permettant la mise en oeuvre du procédé de l'invention ainsi que le magma obtenu suite à la mise en oeuvre de ce procédé.
