“…In the second stage (250 °C < T < 350 °C), large hydrocarbon chains decompose to form low-molecular-weight compounds. In the final stage ( T > 350 °C), polyene further decomposes into a large amount of low molecular weight compounds. − In Figure , we can see the slight difference in the DTG curves of PS (styrene) and PS (utensil). Even though the highest DTG peaks for both samples are the same, complete degradation of PS (Styrofoam) occurs 10 to 15 °C or 0.67–1 min (on average) earlier than that of PS (utensils).…”
