Abstract
Ether-linked amine-terminated polyethers are produced by reacting (1) a polyether polyol in which substantially all of the hydroxyl groups have been replaced with good leaving groups with (2) an aminoalcohol and/or aminothiol and (3) a deprotonating agent. The aminopolyethers obtained by this process are characterized by low viscosities and excellent reactivities over a wide range of molecular weights and functionalities.
