We present results of the phase behavior of [hmim][Tf2N] blends with hydrophobic polyethers that have appreciable CO2 solubility. The polymers studied include poly(n-butyl glycidyl ether), poly(allyl glycidyl ether), and poly(isopropyl glycidyl ether). Phase behavior was probed using DSC, microscopy and turbidimetry. The effect of the pendant functional groups in the glycidyl ether polymers (isopropyl vs. n-butyl, and the presence of the double bond in the allyl version) was investigated using 2D NMR and FTIR spectroscopies.
