Free radical terpolymerization of ( N,N )‐dimethylacrylamide, ethylene‐glycol‐dimethacrylate and N ‐( p‐ or m‐ ethyl‐phenyl)acrylamide leads to para ‐ and meta ‐ethyl‐phenyl‐modified hydrophilic polymer networks. Polymeric networks of different molar ratios are prepared in special molds to give water swellable disc‐ shaped samples. The swelling behavior in water and aqueous cyclodextrin (CD) solution of the obtained samples is described while a distinctive differentiation between the para ‐ and meta ‐ethyl‐phenyl containing networks in CD solution can be found.
