ABSTRACT:
Hydrolytically stable hydroxyl-terminated liquid polymers that are useful in the preparation of polyurethanes prepared by reacting at least one aminoalcohol with a carboxyl-terminated liquid polymer having a carbon-carbon backbone. The hydroxyl-terminated polymers have the formula ##STR1## wherein B is a carbon-carbon backbone, X is HO-- or HO--Y-- a univalent radical obtained by removing a hydrogen atom from an amine group of aminoalcohol containing one primary or secondary hydroxyl group and one primary or secondary amine group per molecule, and the polymers contain an average of greater than 1.5 terminal hydroxyl groups per molecule.
