000087901 520__ $$aThe effects of the size (pseudo-generation number) and nature of end groups on physical and rheological properties were investigated for a series of hyperbranched polyesters based on an ethoxylated pentaerythritol core and 2,2-bis-(hydroxymethyl) propionic acid repeat units. The observed linear dependence of the melt viscosity on the molar mass in the high pseudo-generation-number limit indicated that entanglement effects were substantially absent. Moreover, the marked influence of end capping of the end groups on the physical and rheological properties suggested that intermolecular interactions were dominated by contacts between the outer shells of the molecules, in which the end groups were assumed to be concentrated.
