A series of novel amino-alcohol compounds were synthesized from ethylenediamine and cyclic carbonates derived from different glycidyl ethers and CO₂. The amino-alcohols were applied as chain extender for the preparation of polyurethaneurea (PUU) containing hydroxyl groups. The influence of the amino-alcohols on the structure and property of PUU were studied by mechanical testing, Fourier transform infrared spectroscopy (FT-IR), dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC) and thermogravimetry (TG) et. al. The tensile strength of hydroxyl contained polyurethaneurea CDMEDA-PUU could reach 28.27 MPa, about 260% higher than the hydroxyl shielded one. The results proved that the introduced hydroxyl groups greatly enhanced the hydrogen bonding within PUU and the structure of amino-alcohol had certain impact on PUU performance. The cyclic tensile test results further disclosed the existence of strong hydrogen bonding among the hard segments and the long-range connectivity of the permeable hard domains.

以乙二胺和不同缩水甘油醚和CO _{2衍生的环状碳酸酯为原料合成了一系列新型氨基醇化合物}. 氨基醇作为扩链剂用于制备含羟基的聚氨酯脲（PUU）。通过力学测试、傅里叶变换红外光谱(FT-IR)、动态力学分析(DMA)、差示扫描量热法(DSC)和热重分析法(TG)等研究了氨基醇对PUU结构和性能的影响。人。含羟基聚氨酯脲CDMEDA-PUU的抗拉强度可达28.27 MPa，比含羟基的聚氨酯脲高260%左右。结果证明，引入的羟基大大增强了PUU内部的氢键，氨基醇的结构对PUU的性能有一定的影响。
