Notes:
Ionic diols with varying methylene spacers were prepared from maleic anhydride and linear diols. Reaction across the unsaturated site by aqueous sodium bisulphite was used to prepare the ionic diols. Chain extended polyurethane ionomers were prepared by the reaction of prepolymer based on different polyols and diisocyanates with the ionic diols. The polyurethane anionomers were characterized by FT-IR and FT-NMR spectroscopy. The differential scanning calorimetric results show that Tg of the anionomers shifted towards low values as the ionic content in the polyurethane increases and as the length of the ionic diol increases. © 1996 John Wiley & Sons, Inc.
