Summary of thermal properties of synthesized materials compared to the precursors.
| Material | Onset temperature (°C) | Degradation temperature (°C) | Remarks |
| PMPSgLig-NaMMT | 220 | 220–650 | Loss of water at 30–120°C; gradual degradation, showing decomposition of lignocellulose at 400°C | PMPSgLig-NaMMT | 320 | 425–900 | Loss of water at 30–120°C; gradual degradation | PMAAgLi-NaMMT | 240 | 240–600 | Loss of water at 30–120°C; decomposition of lignocelluloses at 220–420°C, decomposition of grafted polymer at 420–650°C; gradual degradation | NaMMT | 220 | — | Thermally stable within the analytical temperature range used; only lost moisture around 100–120°C and water of crystallization | Lignocellulose | 220 | 340–600 | Loss of water at 30–120°C; fairly rapid degradation |
