  • Cyclodextrin polymers and process for their preparation
    Patent number: 5360899
    Abstract: Hydrophilic, water-dilatable cyclodextrin polymerizates have a high cyclodextrin content and possess good mechanical properties. The cyclodextrin pearl polymerizates are produced by reacting hydroxyalkyl cyclodextrin derivatives with bifunctional crosslinking agents such as epichlorohydrin or diepoxides, followed by hydroxyalkylation of the primary product so obtained. The cyclodextrin polymerizates produced in this manner have mechanical properties appreciably superior to those of known, comparable cyclodextrin polymers.
