DSC measurements carrying out

Nucleus density can be determined from DSC measurements carried out under isothermal conditions at various temperatures. Figure 6.1 shows the relationship between nucleus density and temperature obtained by the above described method. The nucleus density decreases drastically with increasing temperature. Figure 6.2 shows that high nucleus density is important requirement for high quality clarifier. With increasing nucleus density optical properties improve considerably. ... 

The same conclusion can be drawn from the differential scanning calorimetry (DSC) measurements carried out on the same PET/PA6 system [43] the melting peals of PA6 does not appear after prolonged thermal treatment. 

DSC measurements carried out on the PiPP-g-PMMM system (19), showed the presence in the thermograms of two distinct transitions at 0 °C and 120-130 °C attributed to the glass transition temperature of PiPP and PMMA respectively this demonstrates that PMMA is successfully attached to the polyphosphazene matrix during the light-induced grafting reaction.
