Cyclodextrin Complexes of Polymers Bearing Adamantyl Groups: Host-Guest Interactions and the Effect of Spacers on Water Solubility

Thermoresponsive polymer inclusion complexes were prepared by radical polymerization in water of acrylamides bearing adamantyl groups by the use of randomly methylated β‐cyclodextrin (Me‐β‐CD). Aqueous solutions of the resulting polymer complexes show a temperature‐dependent transparency arising from a reversible dissociation above a critical temperature. The rate of the process strongly depends on the distance between the adamantyl groups and the polymer main chain.
