  1. (a) The temperature at which 5 wt% weight loss was recorded by TGA. (b) The temperature at which 10 wt% weight loss was recorded by TGA. (c, d) The percentage of residuals after TGA at a maximum temperature in N2 atmosphere. (e, f) The limiting oxygen index was calculated using LOI = 17.5 + 0.4CY (CY = Char yield) at a temperature of 800 and 1000 °C.
