摘　　要：本文用多种不同吸附剂对聚醚进行了后处理,并探讨了工艺条件对后处理效果的影响。使用混合吸附剂按改进的工艺可以使K^+ 含量<2 ppm,且脱色效果好,产品清澈透明。该法成本低,易操作。Many different sorbents were bested in the process of polyethenoxy ethers posttreatment. And the effects of processing conditions on the posttreatment results were studied. Using the mixed sorbent and according to the reformative process,we obtained the K+ content less than 2 ppm.good decoloration effect and clear transparent products. This process was inexpensive and maneuverable.
