“…Additionally, a new trend in membrane design 14 is the alteration of membrane structure from two-dimensional geometry with a lower degree of potential application to three-dimensional membrane architectures in molecular ensembles 15 . One approach to design sterically hindered node fragments in macromolecular structure is the application of amino ethers of boric acid [16][17][18] . The introduction of steric hindrance effect creates an opportunity to influence polymer architecture and, furthermore, a possibility to control intermolecular interactions, not only between amino ethers of the boronic acid, but also of polymer's macrostructure.…”

Herein we present the structural and mechanical properties of polyurethanes synthesized from amino ethers of boric acid for gas separation. The polymers were characterized by light scattering methods, conductivity measurements, thermal gravimetric analysis, Fourier transform infrared spectroscopy, and atomic force microscopy. Additionally, the permeability of ammonia and carbon dioxide, as well as the selectivity for their diffusion and resultant impurity are presented. The results illustrate the steric hindrance, resulting in a branched architecture borate formation, leads to intermolecular complexation which may assist the polymer in ammonia diffusion selectivity.
