- 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.
