• Studies of thermally assisted interactions of polysulphide polymer with ionic liquids

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.

• Unprecedented exploration of ionic liquids as additives which astonishes the thermal stability of PVC formulations

he use of ionic liquids as additives and an economic and environmentally benign alternative to conventional inorganic and organic additives in poly(vinyl chloride) (PVC) formulation is investigated by using thermogravimetric anal-ysis. The present study deals with an elegant exploration of the resulting thermal proﬁles to disclose the pattern of thermal degradation for $N$-butylpyridinium hexaﬂuorophosphate and PVC formulation as well. Furthermore, non-isothermal kinetic investigations providing sound information about kinetic parameters, such as activation energy and frequency factor by using the Coats–Redfern equation in the temperature range of 593–663 K for $N$-butylpyridinium hexaﬂuorophosphate and 423–473 K for the resulting PVC formulation were performed.
