“…This can be seen from the TGA curve of SBR composite 43 . Figure 8 confirms that SBR/FOSM‐4 will produce alkanes (2941, 2869, 1498 cm −1 ), 44 alkenes (3069, 1604 cm −1 ), 43 aromatics (693 cm −1 ), 45 NH 3 (3304, 947 cm −1 ), 46 CO 2 (2302 cm −1 ), CO (2174 cm −1 , 2102 cm −1 ), 33 H 2 O (3735 cm −1 ) and other gaseous products during pyrolysis. As we all know, according to the Lambert–Beer law, 47 the absorption intensity of a functional group is proportional to the concentration of the gas product containing the functional group.…”
