## SYNOPSIS A series of polyether (PTMO, PEO) polyurethane ionomers having different contents of sodium sulfonate groups in the soft segments have been synthesized. The reaction of transesterification was involved in the incorporation of the sodium sulfonate groups in the polyether. The polyuretha
Fire-resistant polyurethane ionomers successfully synthesized at our laboratory have been proved by infrared spectra. In aqueous solution, the surface tension for fire-resistant polyurethane ionomers made by toluene diisocyanate or isophorone diisocyanate was found to decrease substantially with inc
