    Structural relaxation of polyvinyl acetate (PVAc)

  • Original language description

    Structural relaxation of polyvinyl acetate (PVAc) was studied by mercury dilatometry and differential scanning calorimetry. Tool?Narayanaswamy?Moynihan (TNM) and Adam?Gibbs?Scherer (AGS) models were used to fit numerous experimental data. Single set of volume and enthalpy relaxation parameters describing all performed experiments was found for each model. Furthermore, several non-fitting methods of TNM parameters? estimation (including, e.g., peak-shift method or inflectional analysis) were applied to our data and their critical comparison is outlined. For most methods a good agreement with curve-fitting results was achieved.

    Strukturní relaxace polyvinylacetátu (PVAc)

  • Czech description

    Strukturní relaxace polyvinylacetátu (PVAc) byla studována pomocí rtuťové dilatometrie a diferenciální skenovací kalorimetrie. Experimentální data byla proložena modely Tool-Narayanaswamy-Moynihan (TNM) a Adam-Gibbs-Scherer (AGS), pro každý model byla nalezena jediná sada objemových a entalpických parametrů pomocí níchž bylo možno popsat všechna naměřená data. Dále bylo na naměřená data aplikováno několik nefitovacích metod (včetně peak-shift metody a inflexní analýzy), pro výsledky většiny z nich bylodosaženo dobré shody s hodnotami získanými z přímého proložení experimentálních dat.
