    Notes: Abstract When ethylene-vinyl acetate copolymer, EVA, is heated, a two-stage thermal degradation occurs following its melting. The vinyl acetate content of the copolymer was determined to be 43.8% by using TA 2950 and TA 2050 thermogravimetric instruments. TG/FTIR was used to detect the evolved gas. Acetic acid and trans-1-R-4-R'-cyclohexane were the main products evolved from EVA in the first and second stage, respectively. The apparent activation energies were determined for both stages by differential methods.

    Application of Constant Reaction Rate TG to the Determination of Kinetic Parameters by Hi-Res TG (2000)
    Springer
    Journal of thermal analysis and calorimetry 60 (2000), S. 623-628 
    Details
    ISSN: 1572-8943
    Keywords: activation energy ; constant reaction rate TG ; CRTA ; EVA ; thermal degradation

    Topics: Chemistry and Pharmacology
    Notes: Abstract A simple operation mode to determine the apparent activation energy E a is introduced. E a can be determined with a double-curve method by using a constant reaction rate (CRR) approach of Hi-Res TG. The most appropriate mechanism function f(α) and frequency factor A are determined by a single-curve method when the activation energies provided by the two methods are in good agreement with each other. The deacetylation of EVA copolymer has been used for illustration. Advantages of the CRR are discussed.
