摘要：

En route to intelligent hydrogels: Copolymers of N-isopropylacrylamide containing adamantyl groups can be cross-linked noncovalently with cyclodextrin dimers. This results in thermosensitive hydrogels with cloud points that are lower than those of the pure copolymers. Addition of monomeric methylated cyclodextrin results in an increase in the cloud points but has no significant influence on the viscosity of the copolymer solution.
