Thermal, melting and crystallinity behavior of esters grafted LDPE by thermolysis method

Two different esters were grafted onto LDPE in an inert atmosphere at 160 °C under different experimental conditions by thermolysis method. The order of functionalization, crosslinking and C = C formation were determined by FTIR based kinetics. The percentage ester grafting was determined by using the ratio of RI of carbonyl stretching and C-H bending vibration. The energy of activation for all the three reactions were also determined from FTIR-RI kinetic method. FTIR is used to confirm the structure of ester functionalized LDPE. The thermal properties of the functionalized LDPE were characterized by DSC and TGA like analytical tools.
