摘　　要：本文合成了端胺基聚氨酯(ATPU),研究了ATPU对环氧树脂的增韧作用.实验证明10PHR ATPU对环氧树脂的增韧效果最佳,其断裂韧性GTR由纯树脂的9.76J/m^2增加到51.5J/m^2,且其它性能未明显劣化.ATPU was synthesized in this paper and the toughening effect of ATPU on epoxy resin was studied. It was discovered that the crack tougheness was increased from 9. 76j/m to 51. 5j/m when the resin was toughened with 10 PHR ATPU. with other properties of the resin changed not badly.
