A novel thermoresponsive polymer based on adamantyl-terminated hyperbranched polyglycerol (HPG-AD) is reported. The hydroxy-terminated hyperbranched polyglycerol (HPG) is functionalized by esterification of HPG with 1-adamantanecarbonyl chloride. The resulting HPG-AD shows interesting lower critical solution temperature (LCST) phase transitions in aqueous solution, depending on polymer concentration and AD graft ratio. In addition, the LCST transition can be controlled by adding various amounts of β-cyclodextrin (β-CD) by a host/guest interaction. The adjustable thermoresponsive behaviors are studied by UV-vis spectroscopy and dynamic light scattering.
