摘要: Abstract Using temperature modulated differential scanning calorimetry (TM-DSC) the complex frequency dependent heat capacity C ( ω ) can be measured. is connected to an additional time variable ζ t ), which describes kinetics of processes inside sample. Usage phenomenological or molecular models for allows interpretation measured TM-DSC curves. This illustrated melting Poly(ethylene terephthalate) (PET) and Poly(E-caprolactone) (PCL). The polymers investigated compared a first- second-order phase transition. behaviour in region manifold. different empirical local relaxation process melt quantitative curves described.
