摘要：

In this paper, We Would like to present a novel system of host host-guest hydrogels. By polymerizing adamantyl containing acrylamide monomers (12-15) with water Soluble comonomers. we sythesized Various copolymers bearing guest components. As host system we applied easily accessible beta-cyclodextrin polymers With M,, Values of about 30K-100K g mol(-1). The viscosity oft he resulting hydrogel could be influenced by the concentration of both Substances. by the length of the carbon spacer chain of the guest monomer. by the pH Value or by the conformation of the beta-cyclodextrin polymers. Moreover, the hydrogels stayed stable in Solutions of starch hydrolyzing, enzyme taka-diastase from Aspergillus oryzae.
