ABSTRACT:
The subject invention relates to compositions prepared by oxyalkylation of N-(2-hydroxyalkyl)-aniline as the initiator compound with one or more alkylene oxides at elevated temperatures and in the presence of an alkali metal hydroxide. The resulting compositions have an unsymmetric structure with two functional groups, a secondary amino nitrogen and a hydroxyl group. The initiator compound reacts completely and removal of any residual initiator from the polyol is not required. When the subject invention polyol composition is reacted with an isocyanate, both urea and urethane groups form. The subject polyols may be used in the preparation of polyurethane products as well as nonionic and ionic surfactants.
