A kinetic study of thermal degradation of polypropylene

Degradation study of polypropylene (PP) and bioriented polypropylene (BOPP) in the environment

“…Thermogravimetric analysis (TGA) was used to verify thermal decomposition of polyolefin [35][36] . TG/DTG is capable of identifying changes in crystallinity, carbon chain scission and crosslinking 37 .…”

“…Chawla et al (2006) credits changes in crystallinity in the polymers to reductions in molar mass, probably due to chain β-scission [32][33][34][35][36][37][38][39] . The decrease in the degree of crystallization due to biodegradation suggests that smaller crystals were formed 40,41 .…”

Thermal behavior and pyrolytic degradation kinetics of polymeric mixtures from waste packaging plastics

“…The first step for a suitable design of any pyrolysis reactor is the knowledge of the process kinetics of the input plastic matrices. Many extensive studies on thermal degradation kinetics of single plastics have been carried out [12][13][14][15][16][17][18], and most of them have been developed on the assumption that the reaction can be described by a first or an nth order reaction model. This assumption can result in the Arrhenius parameters deviating from the real ones [19][20][21].…”

The Addition of Aluminum Nanoparticles to Polypropylene Increases Its Thermal Stability

“…Pyro lysis is the standard technique used to study the thermal behavior of polymers, and much interest has been shown in discovering more about the thermal degradation of PP [7][8][9][10][11][12] and its nanocomposites. Thermogravimetric analysis (TGA) can be used to obtain the associated apparent activation energy (E a ) and kinetic model of decomposition [7,11,13].…”
