The decomposition temperature and chain regularity of the pseudopolyrotaxanes increase with increasing amount of CB[6] threaded.
And the major weight loss in the second stage from 400°C to 650°C could be undoubtedly assigned to the decomposition of molecular chain of polymer.
TG and DTG curves of chitosan alone demonstrate the polymer chain decomposition from 197 to 276 °C with maxima at 211.8 and 237.6 °C.
The weight loss starting at around 260 °C, as shown by the TGA curves (Fig. 5), could be attributed to the decomposition of molecular chain of PAAEM.
Between 250 and 450 °C, the decomposition of polymer chain, decomposition/dehydration of nickel acetate, and crystallite formation in the composite microspheres led to a weight loss of 71.4 %, obviously lower than the 92.7 % of template polymer microspheres, due to the remaining of NiO species.
In the temperature region of 120 250 °C, a 49.46% weight loss is observed for the pure PVA film which is identified as the decomposition of side chain and some amorphous carbons decomposition (Lai et al. 2015).
Some groups have proposed that the spinodal decomposition due to chain conformation in the molten state may act as a precursor to crystallization based on these findings.
The second possibility of decomposition is the chain length reduction by one carbon, resulting in the so-called C n−1-alkanes (C8, C9, C15 and C17) via decarbonylation and decarboxylation.
Based on the operant physical mechanisms we develop a constitutive model using a polymer chain decomposition and evolution approach to track the molecular structure changes during simultaneous irradiation and mechanical loading.
The first stage was associated to the resolving of hydroxyl and carboxyl on the surface of f-GNPs and removal of the H2O vapors of the sample; the major weight loss between 600°C and 880°C could be undoubtedly assigned to the decomposition of molecular chain of polymer.
In general, the dimensions of the M-local algebras t M ( L ) can be even smaller than predicted by the upper bounds of Theorem 27 as can be seen in Table 2 for L = 4. Theorem 27 and Table 2 suggest that the prime decomposition of the chain length L will have strong implications on the dimension of t M ( L ).
