Influence of Researchers on the Results of Kinetic Analysis of Thermal Degradation of Polymers

M. Erceg, M. Jakić and I. Krešić


In this paper, the influence of researchers on the results of kinetic analysis of non-isothermal thermal decomposition of four polymers was investigated. Four polymers having different degrees of complexity of the degradation process were analysed. The kinetic analysis was performed by three researchers: one scientific advisor with tenure, one research associate and one doctoral student, all of whom used the same experimental thermogravimetric data. Kinetic analysis was performed using the Netzsch Thermokinetics Professional program. The results unequivocally showed that the researchers have a significant influence on the results of kinetic analysis, since they described the processes of the non-isothermal thermal decomposition of all samples by different kinetic schemes, and thus by different kinetic parameters.
