The melting temperature of a polymer reflects the melting of crystals formed during primary and secondary crystallization, This frequently gives rise to multiple endotherms in a DSC heating scan, where the upper peak corresponds to melting of primary crystals and the lower peak corresponds to melting of crystals formed during secondary crystallization (e.
For example, a 30% glass-filled phydroxybenzoic acid (HBA)/6-hydroxynaphthoic 2-acid (HNA) copolyester LCP has a DSC endotherm from 263[deg.
The thermograms in figure 3 illustrate the changes typically observed in the shape of the melting endotherm peaks due to a combination of crystallization and annealing effects.
The DSC heating curves/melting endotherms were obtained for different ageing conditions and only representative curves for 50[degrees]C + W are given in Fig.
Bakker claimed that all dinosaurs were "automatic" endotherms - animals with fast, stable metabolisms that supply enough internal heat to keep their body temperatures constant.
A single melting endotherm was observed after the annealing process at an optimized temperature and processing time [41, 42].
By increasing the irradiation dose, the degree of branching increases and the branch length decreases [17, 22], There are available a number of reports on the appearance of shoulder or duplicated crystallization/melting curves of LCB PP [32], It is reported that the presence of a shoulder in cooling thermogram is due to the crystal defects which consequently leads to a flattened melting endotherm peak [32-34].
c]) is calculated by dividing the melt enthalpy of samples (the area under the endotherm peak in DSC curve obtained while investigating melting behavior) by the melt enthalpy of the samples with 100% crystallinity ([DELTA][H.
2 K showed a significant difference in the relative area of the lower melting endotherm to the higher melting endotherm.
cc]) associated to the formation of early incomplete crystals, and the multimelting process characterized by two endotherms (142 and 154 [degrees]C) corresponding to PLA phase and a single melt endotherm to lower temperature (130 [degrees]C) for PE phase in ternary blends (19).
In this work, we have observed multiple melting endotherm phenomena in identical PUs prepared from only hard segments in the main backbone.
