An ionic liquid (IL) was synthesized and incorporated into polypropylene (PP) via melt blending. The structure of the IL was confirmed by infrared spectroscopy and NMR spectroscopy. The volume resistance of neat PP and PP/IL blends indicated that the IL had excellent antistatic properties. The tensile strength and impact strength of the PP and PP/IL blends showed that the IL also had good light stability. Thermogravimetric analysis (TGA) was performed in both nitrogen and air, and the effect of the heating rate in dynamic measurements (5°–30°C/min) on kinetic parameters such as activation energy was also investigated. The Flynn–Wall–Ozawa method was used to determine the apparent activation energy for the degradation of neat PP and the PP/IL blended composites. The TGA results showed that the addition of the IL improved the thermal stability of PP, and the kinetic results showed that the apparent activation energy for the degradation of PP/IL was much higher than that for neat PP.
