      The present paper, for the first time, reports analysis regarding the structural interactions of polysulphide polymer with ionic liquids (ILs), which have been studied by thermo-gravimetry analysis (TGA). A systematic thermal analysis of polysulphide polymer has been carried out, based on polymerization and series of ILs like tetrabutyl ammonium hexa-fluorophosphate [TBA][PF$_6$], N-butylpyridinium bromide [Bpy][Br] and 1-butyl-3-methyl imidazolium bromide [Bmim][Br] using a thermal gravimetry analyser. The plausible mechanism of the interactions and thermally induced reactions of polysulphide polymer with ILs has been advanced and discussed. The probable interactions of polysulphide polymer with [Bmim][Br] and [TBA][PF$_6$] are also discussed. The interactions between polysulphide polymer and ILs were confirmed by Fourier transform-infrared spectroscopy, TGA–differential thermo-gravimetry analysis and field emission scanning electron microscopy analysis.
