The ionic species present in 3000 MW {alpha},{omega}-hydroxy poly(propylene oxide), PPO, complexed with divalent metal trifluoromethanesulfonate, CF{sub 3}SO{sub 3}-, {open_quotes}triflate{close_quotes} salts have been studied using infrared and Raman vibrational spectroscopy. The cations considered in this work include magnesium, calcium, zinc, cadmium and lead. The formation of ionic species was studied as a function of salt concentration in complexes with ether oxygenation ratios of 80:1, 40:1, 20:1 and 10:1. The temperature dependence of ionic association was measured in the 20:1 complexes from room temperature to 125{degrees}C. Ionic association was examined by observing bands in the symmetric SO{sub 3} stretching region and the doubly degenerate asymmetric SO{sub 3} stretching mode.
