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:
-
The end group structure of dialkyl polyether was characterized by infrared spectroscopy and nuclear magnetic resonance. Through the test of the physical and chemical properties (heat resistance, viscosity, surface tension) of the dialkyl polyether, the influence of the structure of the dialkyl polyether on its physical and chemical properties was obtained. It was found that with the increase of the termination rate of dialkyl polyether, the heat resistance of polyether became significantly better, the viscosity decreased, the stability of aqueous solution improved, and it had better surface activity.
