The literature data on the melting points of plasticizers proved uncertain; we intended to gather the data by other methods, differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and thermally stimulated discharge (TSD). Results of ten plasticizers are demonstrated.

Thermogravimetric analysis as applied to prediction of plasticizer
A fundamentally new procedure was proposed for evaluating the parameters of plasticizer desorption from flexible-PVC compounds by quantitative description in terms of a developed kinetic model and of TGA data obtained under the conditions of a linear rise in temperature up to the onset of chemical transformation.
- Do plasticizers have melting points?
- The paper deals with the study of plasticizers using different thermal methods. The literature data on the melting points of plasticizers proved uncertain; we intended to gather the data by other methods, differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and thermally stimulated discharge (TSD).
- Can plasticizers predict the properties of plasticized polymer?
- The plasticizers are also tested for the most important properties, e.g., volatility, compatibility, thermal- and oxidative stability, etc. However, we found that the published melting points are unreliable therefore cannot be used for predicting properties of plasticized polymer.
- Which plasticizers are used for TSD measurements?
- The list of plasticizers is given in Table 1. For TSD measurements, 60 gm −2 borosilicate glass fiber filter of 0.2 mm thickness and 2.6 μm nominal pore size was used as scaffold material. Its pore volume is 87 ± 2%. Figure 1 shows the SEM image of the filter.
- What is the depolarization curve of a plasticizer?
- Depolarization curves of plasticizers tested contain a very low temperature transition (TSD low) and a higher one (TSD high) in Table 2. Depolarization curve of DIDP is shown in Fig. 6 in solid line. Resolved transitions are plotted in different dashed lines.
- What is a typical melting peak of a plasticizer?
- Only two curves contain typical melting peak: the DBP and the DUP. Melting of DBP occurs at much higher temperature (− 8.6 °C) than the published value (− 35 °C). Interestingly, no other process can be observed below the melting temperature. DSC curves of plasticizers. * For DPB the scale bar is 2 Wg −1
- Which plasticizers were tested?
- All plasticizers tested were technical quality products, the DEHP high-purity medical grade. The list of plasticizers is given in Table 1. For TSD measurements, 60 gm −2 borosilicate glass fiber filter of 0.2 mm thickness and 2.6 μm nominal pore size was used as scaffold material. Its pore volume is 87 ± 2%.
