Title (EN) PROCESSES FOR SYNTHESIZING CYCLODEXTRIN POLYMER AND PRODUCING CYCLODEXTRIN FILM
(FR) PROCEDES DE SYNTHESE DE POLYMERE DE CYCLODEXTRINE ET DE PRODUCTION DE FILMS DE CYCLODEXTRINE
Abstract:
(EN) A process for synthesizing cyclodextrin polymer either by the reaction of cyclodextrin derivative with polyvinyl alcohol, cellulose or their derivative(s), or by the copolymerization of cyclodextrin derivative with vinyl acetate or methyl methacrylate; and a process for producing cyclodextrin film from the cyclodextrin polymer. The polymer has a high cyclodextrin content, and the film produced from this polymer can be used in the form of a single film without the necessity for using other supporting film, because the polymer itself has a capability of forming film.
(FR) L'invention se rapporte à un procédé, qui sert à synthétiser un polymère de cyclodextrine soit par réaction d'un dérivé de cyclodextrine avec de l'alcool de polyvinyle, avec de la cellulose ou avec un ou des dérivés de ces derniers, soit par copolymérisation du dérivé de cyclodextrine avec de l'acétate de vinyle ou du méthacrylate de méthyle; ainsi qu'à un procédé permettant de produire un film de cyclodextrine à partir de ce polymère de cyclodextrine. Un tel polymère possède une teneur en cyclodextrine élevée et le film produit à partir de ce polymère peut être utilisé sous la forme d'un film en une seule couche, sans qu'il soit nécessaire d'utiliser d'autres films de support, dès lors que le polymère possède lui-même une capacité filmogène.
