Crystallization of Polymers Investigated by Temperature-Modulated DSC

Righetti, Maria Cristina

CNR-IPCF

The aim of this review is to summarize studies conducted by temperature-modulated differential scanning calorimetry (TMDSC) on polymer crystallization. This technique can provide several advantages for the analysis of polymers with respect to conventional differential scanning calorimetry. Crystallizations conducted by TMDSC in different experimental conditions are analysed and discussed, in order to illustrate the type of information that can be deduced. Isothermal and non-isothermal crystallizations upon heating and cooling are examined separately, together with the relevant mathematical treatments that allow the evolution of the crystalline, mobile amorphous and rigid amorphous fractions to be determined. The phenomena of`'reversing' and 'reversible` melting are explicated through the analysis of the thermal response of various semi-crystalline polymers to temperature modulation.
