The thermodynamic relation between heat, entropy of fusion and melting point is used to calculate the melting point of polyethylene terephthalate from the melting points of several series of oligomers. The success of the method depends on the assumption that the heat and entropy of fusion per ...
Both Tm and Ta approach to a value of ca. 3.3 °C higher than the corresponding Tc when the crystallization time tc approaches the starting point. That is to say, the Hoffman-Weeks plot is parallel to Tm=Tc line. The crystallization line became parallel to the melting line when PBS was...

As aninjection mold manufacturer,we will demonstrate...
The present invention relates to a solid chip for melt spinning, which contains a melted mixture of lignin and low melting point polyethylene terephthalate (PET) compounds modified by copolymerization with dicarboxylic acid comonomers. The melt spun fibers of the solid chip accord...
The aim of the present work was to study the crystallization and melting of polyesters using temperature-modulated differential scanning calorimetry (ADSC) and to point out the additional information that can be obtained with this method compared with conventional DSC. ...
5) low melting point 低熔点 1. The low melting point Ga-Ag-Sn liquid state alloy prepared by vacuum melting method was studied. 采用真空冶炼法制备了低熔点的Ga-Ag-Sn液态合金,分析了Ga含量与液态合金熔点的关系。 2. Influences of low melting point and semi - crystalline EVA on the ...
The melting point of O-crystal with zero stress is about 136 °C. Comparing to that in stress increase, the stress window of δ phase is enlarged above the melting line of O-crystal, as the overstress of L↔δ is larger than that of δ↔H. Below the melting line of O-crystal...
