Polyoxyethylenes containing ionic liquid head group may easily be prepared by simple sequence of reactions involving reaction of imidazolium ionic liquids with paraformaldehyde to form imidazolium ionic liquids substituted at 2-position with [BOND]CH2OH group and subsequent anionic polymerization of ethylene oxide after converting hydroxyl groups into alkoxide groups. Up to DPn ∼ 30 degree of polymerization of POE is equal to [EO]/[bhmim] ratio thus it can easily be controlled. Blending of POE-IL with high-molecular-weight POE leads to significant reduction of crystallinity of POE.
