Title:
PROCESSES FOR SYNTHESIZING CYCLODEXTRIN POLYMER AND PRODUCING CYCLODEXTRIN FILM
Document Type and Number:
WIPO Patent Application WO/1991/018023
Kind Code:
A1
Abstract:
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.
