| Abstract: | 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. |

| Keywords: | polyethers end cap NMR thermal stability surface activity |
