摘要
The present invention concerns a process for preparing copolymers of cyclodextrin(s) and/or cyclodextrin derivative(s), characterized by the following operations: (a) preparing a solid state mixture of cyclodextrin(s) and/or cyclodextrin derivative(s) and/or inclusion complex(es) of cyclodextrin(s) and/or cyclodextrin derivative(s) and a poly(carboxylic) acid and/or a poly(carboxylic) acid anhydride or a mixture of poly(carboxylic) acid(s) and/or poly(carboxylic) acid anhydride(s), and optionally, a catalyst; and (b) heating the solid mixture to a temperature in the range 100° C. to 200° C. for a period in the range 1 min to 60 min, preferably 30 min or substantially 30 min. The present invention also concerns soluble and insoluble compounds of cyclodextrin(s) and/or cyclodextrin derivative(s) or their inclusion complexes with at least one poly(carboxylic) acid.
