Isothermal storage test described

Although any other existent isothermal storage testing devices are also useful for the calculation of the SADT for a chemical of the AC type, including every powdery chemical of the quasi-AC type, the device used to perform a series of isothermal storage tests described herein is introduced in this chapter. 

The tests described above were, of course, all performed with the closed cell. However, it has also been ascertained that, when charged in the open-cup cell and subjected to the isothermal storage test performed at a T, of 162.1 °C, 2 g of picric acid self-heats clearly. It is certain that this phenomenon is caused by the air oxidation of picric acid. 

Yu et al. (2011) studied rheology and phase separation of polymer blends with weak dynamic asymmetry ((poly(Me methacrylate)/poly(styrene-co-maleic anhydride)). They showed that the failure of methods, such as the time-temperature superposition principle in isothermal experiments or the deviation of the storage modulus from the apparent extrapolation of modulus in the miscible regime in non-isothermal tests, to predict the binodal temperature is not always applicable in systems with weak dynamic asymmetry. Therefore, they proposed a rheological model, which is an integration of the double reptation model and the selfconcentration model to describe the linear viscoelasticity of miscible blends. Then, the deviatirMi of experimental data from the model predictions for miscible...
