The polymer topologies can affect to the performance of polymeric materials such as chemical and physical properties. In this work, we present the topology-controlled polyethers (i.e. branched cyclic, hyperbranched and linear) and investigated the effect of polymer topologies on their applications such as self-healing materials and adhesive materials. Based on the polymer topologies with boronic esters, the self-healing properties were investigated by scratch tests and the mechanical properties of obtained cured materials were analyzed by rheometer, DMA and tensile tests. Moreover, as an adhesive materials, topology controlled poly(glycidoxy carbonyl benzoic acid)s (PGCs) were successfully prepared and investigated the intermolecular and intramolecular H-bonding interaction depending on the polymer topologies. Interestingly, both cases clearly showed topology-dependent phenomenon and lead to enhance their properties.
