Polyurethane ionomers based on amino ethers of -phosphoric acid.

The etherification of -phosphoric acid with triethanolamine and polyoxypropylene glycol is studied. The reaction process is accompanied by the formation of hyperbranched amino ethers of -phosphoric acid terminated by hydroxyl groups. A specific feature of the chemical structure of the compounds obtained is the existence of ion pairs in their structure separated in space. The reaction of the etherification of -phosphoric acid with glycols becomes possible through the use of tertiary amines. The amino ethers of -phosphoric acid are investigated as a polyol component for the synthesis of polyurethanes with high adhesion characteristics and strength properties. The experimental results presented allow us to relate polyurethanes obtained on the basis of -phosphoric acid amino ethers to polymers of ionomeric nature.
