Polymer Degradation and Stability 2024
Below 360 °C, scission at crosslinking points predominates, forming anhydrides
Above 380 °C, main chain scission produces corresponding fragments
Above 600 °C, formation of low molecular weight substances, high vapor pressure gases, and swelling-inducing liquids
Organic acids formed from 240 °C to 1000 °C
