Despite their seemingly disparate structures, the synthetic reactions which are used to create UHP/HP polymers and ionenes/poly(ILs) are entirely compatible. Careful analysis of UHP/HP polymer synthetic methods and requisite precursors reveals that hybrid, “ionic” UHP/HP polymers are much more readily accessible than they might seem. Our work does not append, tether or graft ionic components onto existing polymer backbones, but rather uses and controls the step-growth chemistries associated with UHP/HP polymers to build entirely new, unexplored polymer architectures in which ionic components are covalently boundd and precisely integrated with rigid/aromatic structural elements within the polymer backbone. Furthermore, these ionene-UHP polymer hybrids can retain ILs within their structures as a means of modifying properties and structure. This presentation will detail our approach to the design and synthesis of UHP ionenes and present selected results associated with our work in gas separation membranes and additive manufacturing.
