2079208 9114710 PCTABS00007 The invention relates to hydrophilic, water-dilatable cyclodextrin polymerizates with a high cyclodextrin content which possess good mechanical properties and to a process for producing them. The cyclodextrin pearl polymerizates of the invention are produced by radical, inversion suspension polymerization of cyclodextrin derivatives carrying methacrylate groups or their copolymerization with suitable comonomers such as hydroxyethylacrylate or hydroxymethylacrylate. Suitable cyclodextrin derivatives can be produced by reacting cyclodextrins or hydroxyalkyl cyclodextrins with methacrylic anhydride or with glycidyl methacrylate. The cyclodextrin polymerizates produced in this manner have mechanical properties appreciably superior to those of known, comparable cyclodextrin polymers.
