| 摘 要： | 利用红外光谱及核磁共振法表征了双烷基聚醚的端基结构．通过对双烷基聚醚的物化性质（耐热性、黏度、表面张力）的测试，得出了双烷基聚醚的结构对其物化性能的影响规律．发现随着双烷基聚醚封端率的提高聚醚的耐热性明显变好，黏度减小，水溶液稳定性提高，具有更好的表面活性．

| Abstract: | NMR and FTIR were used to characterize the structure of terminal groups of the copolyethers. The tests of physical - chemical properties of the alkyl - end - capped EO/PO copolyethers show that the structure of the copolyethers have effect on the physical - chemical properties. We found that thermal stability of the copolyethers further increased and viscosity decreased when the terminal hydroxyl groups were capped by alkyl groups. The surface activity and the stability of water - solubility of alkyl - capped polyethers were superior to hydroxyl - capped one. |
