Pyrolytic decomposition and model-free kinetics analysis of mixture of polypropylene (PP) and low-density polyethylene (LDPE)

Thermal decomposition behaviour of mixtures of polypropylene (PP) and low-density polyethylene (LDPE) with different weight ratios (20:80, 35:65, 50:50, 65:35, 80:20) is studied under non-isothermal conditions at five different heating rates. Presence of synergistic effect is observed for mixture samples with PP composition >40 wt.%. Formation of hydrocarbons (
