Title (EN) BIODEGRADABLE SUGAR-BASED POLYMER
(FR) POLYMERES A BASE DE SUCRE
Abstract:
(EN) A method of making a sugar-based polymer is disclosed. A sugar and an organic acid derivative having at least two carboxylate functionalities are mixed in a substantially non-aqueous organic solvent with a hydrolytic enzyme and, thereafter, the resulting mixture is agitated for a time sufficient to allow for the polymerization of the sugar. The resulting sugar-based polymer has sugar incorporated in the polymer backbone.
(FR) Procédé de fabrication d'un nouveau polymère à base de sucre. On mélange un sucre ainsi qu'un dérivé d'acide organique présentant au moins deux fonctionnalités carboxylate dans un solvant organique non aqueux avec une enzyme hydraulytique et, ensuite, on agite le mélange obtenu pendant une durée suffisante pour permettre la polymérisation du sucre. Du sucre est incorporé dans le squelette polymère du polymère à base de sucre résultant.
