Polyurethanes Based on Modified Amino Ethers of Boric Acid
2020
Using modified amino ethers of boric acid, porous polyurethanes are synthesized, the porous morphology of which is due to the peculiarities of the hyperbranched macromolecular architecture of amino ethers of boric acid. A change in the structure of amino ethers of boric acid by the introduction of terminal bulky substituents with hydroxyl groups contributes to a change in the size and pore size distribution of polyurethanes based on amino ethers of boric acid. It is shown that one of the reasons for the heat-sensitive vapor permeability of porous polyurethanes is the hydrophilic nature of the pore surface. Film samples of porous polyurethanes have proven to be an effective substrate for the targeted cultivation of connective tissue at the cellular level.
