Compositions comprising a blend of an inorganic base, an organic base, a monofunctional organic nucleophile or a multifunctional organic nucleophile and a thermoplastic hydroxy-functionalized polyetheramine can be formed into films and laminate structures by using conventional extrusion techniques. Containers and other molded parts can be fabricated from the films or laminate structures by using conventional fabricating techniques for thermoplastic polymers such as compression molding, injection molding, extrusion, thermoforming, blow molding and solvent casting.
La présente invention concerne des compositions comprenant un mélange fait notamment d'une base inorganique, d'une base organique, d'un nucléophile organique monofonctionnel ou multifonctionnel et d'une polyétheramine pourvue d'une fonction hydroxy. Ce mélange se prête à la formation en films et en structures laminées par le recours aux techniques conventionnelles d'extrusion. Les techniques conventionnelles de moulage à la presse, moulage par injection, extrusion, thermoformage, moulage par soufflage, coulée au solvant permettent la fabrication des récipients et autres pièces moulées à partir de ces films et structures laminées.
