In situ HTFTIR studies showed that the delta form to gamma form transformation temperature occurs well below the glass transition temperature of sPS, which is depressed due to the presence of solvent in the amorphous phase; higher the solvent content in the complex, lower the transition temperature. Glass transition temperatures determined by Modulated differential scanning calorimetry (MDSC) coincide with the transition temperatures, indicating that the delta form transforms into gamma form at the glass transition temperature for these complexes. Such a behavior is very different from the behaviour of the sPS- solvent complexes formed by dichloromethane, chloroform, toluene, o-dichlorobenzene, decalin (cis-trans) etc. and for these complexes the transition occur well above the T(g).</p>10aCrystallization10aglass transition10ainfrared spectroscopy10aSyndiotactic polystyrene1 aNaidu, Sudhakar1 aRamesh, N., C.  uhttps://library.ncl.res.in/content/studies-effect-glass-transition-crystalline-transition-syndiotactic-polystyrene-solvent-0
