- 69 - ABSTRACT Provided are a cyclodextrin polymer containing cyclodextrin in the backbone chain of a high-molecular weight compound selected from a polyurethane, a polyurea, an unsaturated polyester, a polyester, a polycarbonate, a polyamide and a polysulfone, as well as a cyclodextrin membrane prepared using said polymer. In accordance with the present invention, an increased amount of cyclodextrin unit can be immobilized and the function thereof is significantly improved; further, by using a specific high-molecular weight compound, the polymer obtained is rendered insoluble in water, etc. and yet decomposable with enzymes and it can accordingly be used as a degradable polymer. Further, there can be provided a cyclodextrin membrane which contains a large extent of cyclodextrin and which can be used alone as a membrane.
