Any other information on results incl. tables

The sample exhibited two exothermal events with average onsets of 469.56 K (196.4 °C) and 623.76 K (350.6 °C). A small endothermic event or possible Tg was observed below 150 °C. To be conservative, the onset of the first exotherm is defined as the start of deviation from the baseline. The extrapolated onset on the exotherm is at a higher temperature of 538.73 K (265.6 °C) average. The average heat of the first exotherm is 152.4 J/g and does not completely return to baseline prior to the start of the second exotherm. The average heat of the second exotherm is 204.9 J/g. The results are summarized in the following table.

 

Replicate #	Exotherm, Onset, K	Peak of Exotherm, K	Heat of Exotherm, J/g
1	470.58 (197.4 °C), 623.83 (350.7 °C)	594.54 (321.4 °C), 631.64 (358.5 °C)	161.0, 208.5
2	468.54 (195.4 °C), 623.69 (350.5 °C)	597.20 (324.1 °C), 631.83 (358.8 °C)	143.7, 201.2
Average	469.56 (196.4 °C), 623.76 (350.6 °C)	595.87 (322.8 °C), 631.74 (358.7 °C)	152.4, 204.9
