Potential Synergies of Tailored Branching and Intermolecular Interactions: From Gene Transfer Agents to Elastomers and Fibers

Branched macromolecules offer the versatility of enhanced reactivity and processibility due to a more compact, globular structure. Both solution and melt rheological studies were used to define the influence of both branching and the introduction of intermolecular interactions. Self-complementary hydrogen bonding was introduced to sub-micron fiber surfaces using electrospinning operations. In addition, branched topologies also permitted the incorporation of higher levels of therapuetic reagents due to the lower solution viscosity. Highly branched elastomers were also prepared when a well defined concentration of urea groups were located at the periphery of the branched macromolecule. This presentation will highlight recent synthetic efforts with a focus on the advantages of branched architecture in diverse, high performance, applications.
