Coupled DTA-TGA-FT-IR investigation of pyrolytic decomposition of EVA, PVC and cellulose
Résumé
The behavior of individual polymers (EVA, PS, PVC and cellulose) was investigated under pyrolysis at different heating rates. A kinetic model is proposed for the weight loss and compared with the experimental results and the kinetic parameters were determined and compared with the available published data. IR spectrometric analysis was used to follow the evolution of the gaseous pyrolysis products versus the temperature. Analysis of online Fr-IR spectra confirmed the initial loss of acetic acid for EVA and one HCl for PVC.
