摘 要:利用核磁共振法表征了双丁基聚醚的端基结构。通过对双丁基聚醚的物化性质的测试,得出了双丁基聚醚的结构对其物化性能的影响规律。随着封端率的提高聚醚的耐热性明显变好,水溶液稳定性提高,具有更好的表面活性。NMR was 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 effects on the physical-chemical properties. Thermal stability of the copolyethers was further increased 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.
