ABSTRACT:
Ether-linked amine-terminated polyesters are produced by reacting (1) a polyester 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 aminopolyesters obtained by this process are characterized by excellent reactivities over a wide range of molecular weights and functionalities.
