(Figure Presented) The collapse transition of thermoresponsive dendronized polymers was characterized on a molecular scale by CW EPR spectroscopy. Aggregation of the polymer is triggered by dynamic structural inhomogeneities of a few nanometers, and the dehydration of the polymer chains proceeds, despite the sharp phase transition, over a temperature interval of at least 30°C (see picture). © 2010 Wiley-VCH Verlag GmbH & Co.
