Notes:
DTA (differential thermal analysis) traces for various kinds of polystyrene and substituted polystyrenes, including bulk-polymerized, monodisperse, and isotactic samples, have been recorded below the glass temperature. It has been shown that the β transition is dependent upon polymer structural modification, traces of water or solvent, and sample thermal history. The experimental data presented here support the conclusion that the β transition is due to conformational changes involving backbone motions and phenyl ring reorientation.
