“…The thermal decomposition almost ended once the temperature exceeded 450 °C. The finding above was consistent with the results in previous studies . However, the temperature at which 5 wt% loss of 30‐PC/PS occurred was 373 °C which increased by 25 °C compared with pure PS.…”

“…The finding above was consistent with the results in previous studies. [23,24] However, the temperature at which 5 wt% loss of 30-PC/PS occurred was 373°C which increased by 25°C compared with pure PS. This result was observed mainly due to the fact that the good heat-resistant PC hindered, to some extent, the heat transfer inside the PS matrix and pyrolysis product release.…”

In this study, a facile method to recycle wasted expandable polystyrene (PS) into polycarbonate (PC)/PS bead alloys is described in this paper, and compared with melt extrusion method. Results showed that the initial decomposition temperature of composite with 30 wt% PC increases by 25 °C and simultaneously enhances by 37.6% in tensile property compared to the neat PS via solvent evaporation method, however, a substantial drop in molecular weight with melt extrusion method. The solvent evaporation method provided several advantages, such as easy operation, low energy consumption, low contamination, high purity and high product yield. The expended solvent was recovered using an evaporation process that was put into practice along with the emulsification, making the process more productive and sustainable.

“…Recently, Krauze et al [4] have qualitatively studied thermal degradation of PS in air or nitrogen in relation to temperature (300 o C to 600 o C). In the nitrogen atmosphere, styrene was found to be preferentially formed at the low reaction temperature, whereas, at 600 o C, substantial amounts of toluene, ethylbenzene, α-methylstyrene, diphenylpropane, 1,2-diphenylethylene, styrene dimer, 1,4-diphenyl-1,3-butadiene, 2-phenylnaphthalene, and m-terphenyl were found to have been additionally formed.…”

-Syndiotactic polystyrene was degraded in an atmosphere of N 2 or H 2 at 375 or 400 o C in the presence of transition metal catalysts (Cr, Ni, Mo, Co or Fe) on the support (Al 2 O 3 , SiO 2). Styrene, ethyl benzene, α-methylstyrene, cumene, toluene, benzene as well as bi-and tricyclic hydrocarbons were found in the reaction products. Effects of degradation conditions on the products compositions were discussed. The highest yield of styrene monomer (>80 %) was reached when iron-based catalysts were used.

“…In the thermal analysis of acrylonitrile polymerization and cyclization in the presence of N,N-dimethylformamide, Aviles et al identified occluded molecules of DMF and several compounds containing nitrogen that were produced during the thermal degradation (116). Krauze et al identified 64 products from the thermal degradation of polystyrene in nitrogen and in air and at several different temperatures using Py-GC/MS and Fourier transform infrared spectroscopy (117).…”
