Maximum decomposition temperature

Thermal degradation studies of EB-cured terpolymeric fluorocarbon rubber [430] by nonisothermal thermogravimetry in the absence and presence of cross-link promoter TMPTA reveal that thermal stability is improved on radiation and more so in the presence of TMPTA. Initial decomposition temperature, maximum decomposition temperature and the decomposition... 

Table 1 summarizes the catalysts physisorption properties, the MWCNTs yields and their maximum decomposition temperatures. MCM41 produces amorphous carbon phases with higher thermal stability. Some authors have obtained CNT using only the MCM41 as a template [11, 12] but the reaction was carrying out at higher temperatures and its CNT yield was lower than the one obtained with mesoporous catalyst containing metallic incorporation as in our work. 

In addition, the onset thermal degradation temperature and the maximum decomposition temperature of a composite with 0.75% of graphene oxide increase by 25 °C in comparison to neat PEN. Also, the mechanical and thermal properties of the PEN composite films can be further enhanced by a crosslinking reaction of the nitrile moieties [49].

As shown in Figure 14.1b two maximum decomposition temperatures are observed corresponding to the two different decomposition steps chain scission at 232 °C and unzipping at 251 °C. The final pyrolysates are not carbon dioxide and propylene oxide, but cyclic propylene carbonate and 1,2-propanediol.
