Calorimetric Studies of Drawn Polyethylene Terephthalate,ransition; at high strain, both chain alignment and uncoiling occur and produce crystallization at these temperatures. At higher temperatures and high strain, the uncoiling is too small to allow crystallization. Annealing a drawn sample under strain resulted in an increase in uncoiling which is proportional to the strain.作者: fringe 時(shí)間: 2025-3-23 04:40
Glass Transition Temperature Measurement of Elastomers,his process which appear in the DTA thermogram.
