发明名称 Contact lenses made from lipophilic cyclodextrines
摘要 <p>The present invention relates to a contact lens which contains a crosslinked cyclodextrin derivative which has been rendered lipophilic and which is characterised by repeating units of the formula V <IMAGE> in which n is a number from 6 to 15, each of the R<1> radicals is, independently of the others, R<2> or R<7>, where at least one R<1> radical of the (3 times n) R<1> radicals has the meaning of R<7> and the remaining R<1> radicals are hydrogen or have the meaning of R<2>, in which R<2> is unsubstituted or halogen-substituted alkyl or alkyl-substituted aryl, and in which R<7> is a divalent or polyvalent radical of the formula VI <IMAGE> in which x is a number from 1 to 10,000, R<4>, R<5> and R<8> are, independently of one another, hydrogen, alkyl, unsubstituted or halogen-substituted alkylene or alkenylene, phenyl or hydroxyl, with the proviso that in one radical of the formula VI at least two of the radicals R<4>, R<5> and R<8> are unsubstituted or halogen-substituted alkylene or alkenylene. The invention likewise relates to the use of such crosslinked lipophilic cyclodextrin derivatives for producing contact lenses.</p>
