摘要：
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. (Figure Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
