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.

Selective oxyalkylaton of N-(2-hydroxyalkyl)-aniline

The subject invention relates to alkylene oxide adducts of aniline prepared by reacting an alkylene oxide with an aniline in the presence of preferably at least 0.1 part of alkali metal hydroxide per 100 parts by weight of aniline. The resulting compositions may be used in the preparation of polyurethane products, such as rigid polyurethane foams, and may also be used as nonionic surfactants.

Polyurethane products based on alkylene oxide adducts of aniline having

The subject invention relates to adducts of vicinal toluenediamine prepared by:

Alkylene oxide adducts of vicinal toluenediamine

Alkylene oxide adducts of aniline having reduced viscosity

The subject invention relates to polyol compositions comprising the reaction product prepared by reacting from 4 to 9 moles of propylene oxide per mole of toluenediamine by weight at temperatures greater than 140.degree. C. in the presence of at least 0.6 parts of alkali metal hydroxide per 100 parts by weight of toluenediamine, with the proviso that at least 0.8 part by weight of alkali metal hydroxide is used if the toluenediamine is 2,4-toluenediamine, or 2,6-toluenediamine, or mixtures thereof.
