    Initiation reactions in thermal polymerization of vinyl monomers in the molten state (1984)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 22 (1984), S. 3217-3224 
    Details
    ISSN: 0360-6376

    Topics: Chemistry and Pharmacology
    Notes: Evidence of the initiation process during uncatalyzed thermal polymerization of vinyl monomers is presented. DSC studies reveal a prominent endothermic effect just before the polymerization exotherm, which is substantiated by the identification of the free radicals produced in the initiation by a quick quenching technique and subsequent detection by ESR at low temperatures.

    Thermal polymerization of acrylamide by differential scanning calorimetry (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 19 (1981), S. 2367-2375 
    Details

    Notes: Thermal polymerization of acrylamide was studied by differential scanning calorimetry. Latent heat of fusion ΔHf and enthalpy of polymerization ΔHp values were found to be 36 and -18.0 kcal mol-1, respectively. The overall activation energy E for the polymerization was calculated to be 19 k cal mol-1 up to 60% conversion. The added free-radical inhibitor (benzoquinone) was found to desensitize the thermal polymerization of acrylamide suggesting the polymerization to be a free-radical type. The existing rate equation for the heterogeneous bulk polymerization in the presence of initiators has been modified for the thermally initiated bulk polymerization of acrylamide. The experimental overall E value was found to agree well with the calculated E value when considering only the propagation and termination steps, thereby suggesting the process to be similar to postpolymerization of acrylamide.
