Abstract
  • By analysing the specific heats and the mechanical characteristics of poly(methyl methacrylate) (PMMA) and poly(vinylidene fluoride) (PVDF) amorphous single-state blends in the glass transition region, it has been found that increasing PVDF content cause a small reduction of the fragility of these systems. The degree of fragility has been evaluated from DCp/Cp,l, the normalized change of the heat capacity at Tg, and by modelling the mechanical aa-relaxation. The observed behaviour has been ascribed to a more coherent structure of the blends due to strong specific interactions between PMMA and PVDF polymeric chains. (literal)
