This invention discloses the composition and preparation of imidazolidone modified polyetheramines. The alkyl polyetheramine is derived from 2-isopropylaminoethylamine and urea. N-isopropyl-2-imidazolidone is the intermediate product, which is alkoxylated and aminated to prepare the N-isopropyl imidazolidone polyetheramine. This invention also discloses the composition and preparation of oxazolidinone modified polyetheramines by reductive amination of polyols derived from 4-ethyl-4-hydroxymethyl-2-oxazolidone. The products of this invention have been tested in epoxy resin applications and improved properties have been demonstrated. These products may also be useful in polyurea applications.
