ABSTRACT The present thesis deals with the development of new branched polymer architectures containing hyperbranched polyglycerol. Materials investigated include hyperbranched oligomers, hyglycerols containing functional initiator-cores at the focal point, well-defined linear-hyperbranched block copolymers and also negatively charged hyperbranched polyelectrolytes. Hyperbranched oligoglycerols (DP = 7 and 14) have been synthesized for the first time. The n materials show narrow polydispersity (M /M ca. 1.45) and a very low content in cyclic w n13homopolymers. C NMR evidences the dendritic structure of the oligomers and the DB could be calculated (44% and 52%).
