✦ Synopsis

A novel method for the preparation of immobilized ␣, ␤, or ␥-cyclodextrins on polypropylene nonwoven supports has been previously presented. The obtained new materials were prepared by graft-polymerization of glycidyl methacrylate onto polypropylene after activation of the support by the electron beam technique, followed by the coupling of cyclodextrins with the epoxide groups. The structure of the resulting materials is characterized in detail using Fourier transform infrared spectroscopy, solid state nuclear magnetic resonance analysis, differential scanning calorimetry, thermogravimetric analysis, and optical microscopy.
