Modulated temperature techniques allow to separatethe reversing and non-reversing contributions of material transitions. To investigate reversible crystallization and melting of isotactic polypropylene (iPP) at microstructural level, in this research, modulated temperature Fourier transform infrared (MTFTIR) and quasi-isothermal FTIR (QIFTIR) analyses are used.By following the intensity variation of iPP regularity bands, associated with 31 helix structures of different lengths (n repeating units), MTFTIR evidences that, independently from helix length, a reversing coil–helix transition takes place few degrees below the non-reversing crystallization onset. By comparing spectroscopicand differential scanning calorimetry experiments performed ...
