ABSTRACT:
The invention concerns a method for the preparation of polyoxyalkylene compounds wherein each compound has one primary amine group and one primary hydroxyl group. The method comprises alkoxylating a t-butyl ethylene, propylene or butylene glycol then aminating the product. Finally the t-butyl group is cleaved by an acid. The compounds of the method of this invention are useful in urethane/urea plastics including foams, elastomers and coatings.
