    Thermal decomposition kinetics of poly(acrylic acid-styrene oxide) copolymer using thermogravimetric analysis
    (Marcel Dekker Inc, 2003) Çolak, N; Yagan, A; Tez, Z
    Kinetic parameters for the thermal decomposition of poly(acrylic acid-styrene oxide) copolymer were investigated with the use of a dynamic thermogravimetric analysis (TGA) technique. In this study, nine samples were synthesized in different conditions. TGA thermograms of the samples were recorded in the flow of nitrogen (20 mL.min(-1)) at four heating rates 2, 5, 10, and 20degreesK.min(-1). The activation energies (E), pre-exponential factors (A), and reaction order (n) were obtained from the thermograms. The activation energies changed from 161.86 kJ.mol(-1) to 285.74 kJ.mol(-1), the pre-exponential factors are also in the range of 1.38 x 10(14) to 1.99 X 10(29) min(-1) and reaction order n is 3 for the whole samples.
