Abstract

Abstract: A versatile approach to dendritic polyesters and their use in the preparation of two different types of novel macromolecular architectures represent dendritic block copolymers is described. The chemistry developed for the synthesis of dendritic polyesters involves generation growth through an esterification step using dicyclohexylcarbodiimide (DCC) and 4-(dimethylamino) pyridinium p-toluenesulfonate (DPTS) followed by activation of the ...
