Abstract

AbstractHigh‐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 CC formation reactions were determined from the relative intensities of carbonyl stretching vibration and CH 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.
