摘要
A novel polyoxyalkyleneamine with high reaction activity used in sprayed polyurea elastomer was synthesized by the reaction of amino-crotonic acid ester. The reaction process includes two steps: the esterifying reaction and the aminating reaction. The products of the two steps were respectively characterized by FT-IR, NMR. Then factors determining the color and viscosity of the product and its conversion ration were also discussed.
