High‐density polyethylene (HDPE) was graft functionalized with two different mercaptoesters in an inert atmosphere at 160°C under different experimental conditions by thermolysis method. The order of functionalization, crosslinking, and CC formation reactions were determined from the relative intensities of carbonyl stretching vibration and CH bending vibrations. FTIR, DSC, and TGA analytical tools were used to characterize mercaptoester‐functionalized HDPE. A plausible reaction mechanism is proposed here to explain the experimental results obtained. POLYM.
