    Thermal degradation study of poly(vinyl chloride): Kinetic analysis of thermogravimetric data (1993)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 50 (1993), S. 1565-1573 
    Details
    ISSN: 0021-8995
    Keywords: Chemistry ; Polymer and Materials Science

    Notes: The thermal degradation of a poly(vinyl chloride) (PVC) resin was studied using a non-isothermal thermogravimetric technique. Kinetic parameters such as activation energies, reaction orders, and preexponential factors are calculated using integral and differential methods reported in the literature. Advantages and disadvantages of these methods are discussed in order to characterize PVC. © 1993 John Wiley & Sons, Inc.

    New mathematical model on the thermal degradation of industrial plastisols (1996)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 60 (1996), S. 2041-2048

    Notes: The thermal degradation of some plastisols [poly(vinyl chloride) and plasticizer mixtures] normally used in the toy industry was studied using a nonisothermal thermogravimetric technique. Some kinetic parameters such as activation energies are calculated according to some methods reported in the literature. A mathematical model based on considerations of the plasticizer amount was proposed to foresee the thermal degradation behavior of plastisols mostly used in the toy industry. Activation energies calculated according to the proposed model agree reasonably well with experimental results in a broad range of plastisol composition. © 1996 John Wiley & Sons, Inc.
