ABSTRACT This invention relates to active hydrogen- -containing compositions comprising a relatively high equivalent weight compound having hydxoxyl and/or amine groups and a secondary amine-terminated adduct of a primarily monofunctional primary amine compound and a polyepoxide and to polyurea-containing polymers prepared by reacting the active hydrogen-containing compositions with polyisocyanates. Polymers of this invention have high impact strength, high flexural modulus and high heat distortion temperatures. These polymers are especially useful as structural polymers as well as static or dynamic elastomers.
