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
