Porous polyurethanes based on hyperbranched amino ethers of boric acid

Abstract

Novel polyurethanes with hierarchical supramolecular structure were synthesized via polyaddition reaction of amino ethers of boric acid and polyisocyanate.

Experimental Evaluation of the Efficiency of Membrane Cascades Type of “Continuous Membrane Column” in the Carbon Dioxide Capture Applications

“…The most promising alternative to the chemical absorption method are technological solutions based on the membrane gas separation method, since these processes are characterized by energy efficiency [7][8][9], ease of scaling, environmental friendliness, and the possibility of "tuning" the process by selecting the most efficient membranes and varying the configurations of membrane devices. Attracted by the economic and environmental advantages of membrane technology, many researchers [10][11][12][13] focused on two areas of investigation, the search and creation of new materials (membranes) [14][15][16][17][18][19] and the designing of new membrane processes and devices [20][21][22][23][24].…”

Synthesis and characterization of amphiphilic branched silica derivatives associated with oligomeric medium

“…These polymers are of interest due to their high gas transport characteristics. [48][49][50][51][52][53][54] The specic characteristics of theirs supramolecular structure is polyisocyanate blocks of acetal nature (O-polyisocyanates) as a component with a rigid chain. A scheme of polymers synthesis by the reaction of Microporous polymers modied with ASiP was investigated using FTIR spectroscopy.…”

Synthesis and Study of Gas Transport Properties of Polymers Based on Macroinitiators and 2,4-Toluene Diisocyanate

“…Furthermore, apparatuses should be characterized by simple hardware design. Thus, the high purification of gases is a potential separation field in which membrane technology can be successfully applied individually and as part of hybrid processes [8,9,10,11].…”
