“…The improved separation by the GC/MS makes data interpretation easier than TG‐MS. This allows the separation of fairly complex mixtures with minimal sample preparation by using the TGA to volatilize components 51, 52.…”

The objectives of this paper are to review the thermal degradation and stability of starch and starch‐based materials, including both fundamental sciences such as detecting techniques, the effect of amylose/amylopectin content in starches and starches modifications, as well as the effect of different processing environments, such as an open or sealed system, and shearless or shear stress conditions. The decomposition temperature of starches was increased with increasing amylopectin content in an open system. In the open system, the initial water content did not affect the decomposition temperature because all water had evaporated from samples prior to reaching the decomposition temperature. Two decomposition temperatures were observed in the sealed system: the first at lower temperature represents long chain scission; and the second at higher temperature involves decomposition of glucose ring. In the sealed system, the first degradation was increased with increasing amylopectin content. There is no observable difference of the second degradation for the samples containing different amylose/amylopectin ratios. The higher the moisture content is, the lower the second decomposition temperature is detected in the sealed system. Significant shear degradation was observed in amylopectin component of starch, while high amylose starch proved less sensitive to shear stress. The achievements in this area have increased the knowledge of polymer science, in particular to understand the degradation of natural polymers.

“…While TG-MS was commonly used to study the release pattern and dynamic behavior of volatile components in the combustion of biomass, stalks and coal [37][38][39][40], it is rarely applied to oil and gas exploration field previously. This study aims at studying the generation characteristics of HCs and non-HCs in the thermal decomposition of coal of Shahezi Formation and its late gas potential under open anhydrous, high temperature (up to 1000°C) programmed pyrolysis apparatus (TG-MS).…”

“…It is a simple and fast method in order to verify the thermal properties of the studied compounds. This method is often connected with the spectroscopic methods which make it possible to specify the type of the volatiles emitted under decomposition of the heated compounds and thus their potential decomposition mechanism [40][41][42][43][44][45][46][47].…”

The simultaneous thermal studies (TG/DTG/DSC) coupled with the FTIR analysis of the gaseous decomposition products created under oxidative heating of starch-g-poly(neryl acrylate) and starch-g-poly(geranyl acrylate) copolymers have been presented. To these studies, the copolymers with the following grafting percents (G) were selected: starch-g-poly(neryl acrylate) copolymers: 36.6 ± 0.3%, 40.3 ± 0.4%, 42.8 ± 0.4% and starch-g-poly(geranyl acrylate) copolymers:28.9 ± 0.2%, 32.4 ± 0.6%, 35.6 ± 0.4%. The performed tests proved that the thermal resistance of the copolymers was strongly dependent on their G values, despite a small difference in the G values between the samples. The slight increase (ca. 6.2-6.7%) in the G value caused the significant drop of the thermal stability of all the studied materials. The TG/DTG/ DSC studies confirmed at least three-stage decomposition mechanism of the copolymers where simultaneous pyrolysis, oxidation, dehydration and decarboxylation processes took place. The TG/FTIR analyses showed the emission of various structure fragments; among them, one can mention the creation of some organic fragments such as aldehyde, acid, alkene, alkane, furan fragments, CH 4 and inorganic species (CO 2 , CO, H 2 O) as a result of the oxidative decomposition processes of the studied copolymers. In addition, the conducted studies demonstrated similar decomposition course and mechanism for both types of the copolymers, regardless of the monomer type used to the graft process.
