摘　　要：采用氨基丁酸酯法合成了可用于喷涂聚脲弹性体的高活性端氨基聚醚。整个反应分为酯化和氨化两步,并用红外光谱、核磁共振、元素分析对两步的产物分别进行了表征,最后探讨了影响端氨基聚醚颜色、黏度及转化率的主要因素。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.
