Evaluation Methods for Stabiliy of Polymer Solution

For evaluation of stability of polymer solution, this paper introduces three methods under saturated oxygen and under control oxygen co ntcnt,then analyzes their merits and demerits,so one method among them--the intergral deoxidization and single string evacuation method is selected,it is accurate,simple and rapid.The rcsults show that different method produces different result. But under control oxygen content, the stability of the solution can be distinctly stengthened.
